The tape disappears from his backpack, and he promises to look for it.
Zach continues to encourage Claire to take her powers seriously. Claire says that she just wishes to live a normal life.
Claire confides in Zach about what Brody did to her at the bonfire. He tries to persuade her to report it, but she swears him to secrecy.
Zach walks Claire home before her meeting with her biological parents, Hank and Lisa. They discuss how Claire might broach the topic of her powers with them. Zach confesses that he hopes her parents do not have powers, because it makes her more special. She accuses him of flirting with her but he denies it.
Zach comes over unannounced to Claire's home to give her back the tape that disappeared from his backpack. He tells her he found it under his bed while looking for his PSP even though he checked the bed "like fifty times". He is riding his bike while Claire is chasing her brother after Lyle finds out her abilities, and comes to her aid. Claire and Zach chase Lyle into the Bennet SUV.
Zach helps Claire win Homecoming Queen by getting the 'freak' vote; all the unpopular people voting for the unpopular candidate. While Claire is grounded by her foster-father to avoid her getting killed, Zach sends her a text message saying he's outside her window. She opens it to see him, and he says "I'm here to rescue you". Zach and Claire start talking about what was said about him at school earlier that day (Jackie implied that he was gay). During their conversation, he says he is happy with who he is and has accepted the 'freak' inside. He says that Claire should accept the 'freak' in her, and be happy with who she is.
Zach brings Claire all the tapes that they made of Claire's experimentations with her powers. She destroys them, then tells Zach that her father knows that Zach knows about Claire's powers, and asked her to make sure that Zach wouldn't talk to anyone about them.
Later, Claire calls Zach and asks him to meet her on the football field; she is scared because Lyle has no memories of her powers. Zach accuses her of calling him "out of the blue" after "not talking to [him] since sixth grade;" Zach's memory has obviously been erased by the Haitian.
As Union Wells opens again after the death of Jackie, Claire meets up with Zach in the hall. They talk and Zach comments that lately there are a lot of things he can't remember, but he shrugs it off with a comment about the water. Claire asks Zach to look at her and tell her if he believes they could ever be friends. Zach looks at her briefly and then says plainly that he doesn't think so.
Some time later, after Claire has talked to the Haitian, she once more seeks him out and brings him to the abandoned refinery where they originally filmed her tape. There she tells him to take his camera and film her, as she climbs up the construction and jumps once more.
At the Bennets' home, Zach helps Claire search for clues about her father's deception on the family computer, but they're unable to find anything. When Mr. Bennet arrives home unexpectedly, Claire and Zach pretend to be working on a school project about manatees.
Later, at the Burnt Toast Diner, Claire and Zach review newspaper articles from 14 years ago. Zach finds an article about a fire in an apartment in Kermit, TX in which a woman named Meredith Gordon was killed, supposedly along with her 18-month-old daughter. Zach theorizes that the kid was actually Claire, and suggests Claire look for one of Meredith's relatives in order to find out more about her parents and possibly even find out who her father is.
Claire calls Zach later to update him on her progress looking for one of Meredith's relatives, but is interrupted by her father.
Zach helps Claire with her plan to see her birth mother without anyone finding out; they use their manatee research project as an excuse. Claire's mom questions Zach about the condition of his car, and when he tells her it has had its oil changed and his only tickets are parking tickets, she lets them go.
At his home, Zach answers the door and sees Elle come in. She tells him her name's Cindy and he said he would let her see his fourth period English notes, but Zach doesn't recall that happening. He watches Elle grab him on the shoulder and make a ball of electricity in her hand as she tells him to hand over the tape. Noah steps in and pistol whips Elle. Zach thanks Noah for saving his life, and then asks him what his friend is doing there. Noah tells him he's going to make sure Elle doesn't bother him anymore. Zach is then confronted by them as Noah asks where the tape Elle mentioned is.
Prior to the premiere, Zach is introduced through his myspace page. He says that he is a 18 years old coin-operated-boy, living in Odessa, Texas and going to the second class of Union Wells High School. He says that he has a very poor social circle, being friend especially with that one girl. He lists his interests and details where he say he is a Wiccan. He comments on Claire's page, asking if she did anything special lately. He then starts posting in his page, saying that he has been to the San Diego Comic-Con. Claire comments, asking Zach to borrow his video camera and demands his assistance to use it.
Following Hiros, Zach is very happy to have over a 1000 Myspace friends.
Lastly, following Fallout, Zach has no memories of his relationship with Claire of the few last weeks. He thinks that the cheerleaders stole his Myspace password and decided to play some kind of prank with him, messing up with his account and placing Claire as one of his top friends. He is confused about the crystal meth behavior of Claire, back at school.
Prior to the premiere, Zach comments on Claire's page, asking if she did anything special lately. She says that there is nothing between Zach and her, and that they are simply childhood friends.
Following Genesis, Claire is worried about not being able to find Zach.
Lastly, following Fallout, she notices that even everyone close to her started to be distant, even Zach. But she hopes to see him when school starts again.
"How are you, Zachary?"
"I'm all right. Claire keeps punching me, though."
"Oh, is the gay boy your date? You should tell him that only one of you gets to wear the tiara!"
"You've got to embrace your inner freak."
- Unless he was driving illegally, Zach is at least 16 because he drives Claire to Kermit to see Meredith without another licensed adult driver in the car. (The Fix)
- Early comments from Zach led to a great deal of fan speculation concerning his sexual orientation. In an article in Out, Tim Kring confirmed that he originally intended Zach to be gay. However, NBC's publicity department and Thomas Dekker's management have both claimed that the character is straight. Zach has never explicitly stated his sexual orientation.
- At the Heroes Q&A at Wizard World Los Angeles, it was revealed that Thomas Dekker's management "didn't want him to be playing a gay character" for career reasons. It was also acknowledged that they'd originally conceived of the Zach character as gay, and that the ambiguity was a result of an "unfortunate miscommunication." 
- Zach's MySpace page has been updated to reflect that he suspects a prank from the cheerleaders. He references Claire being added to his friends and things being changed, added and removed even though he has no memory of doing it.
- Thomas Dekker, on his MySpace page, made a bulletin entitled "The Truth About Heroes" explaining the sexuality of the character Zach and his absence on new episodes of Heroes. In the bulletin, Thomas explains that he has previously played gay characters (at ages 12, 15, and 17) and that neither him nor his management have ever had a problem with him playing a gay character. He said he created and developed the character Zach to be heterosexual and wanted him portrayed as an outcast with a burning love for Claire, based on the original script which stated that Zach was in love with Claire. Thomas goes on to state that he was never under any contract with NBC and was hired per episode. He was no longer allowed to be cast in episodes for Heroes after he landed the part of John in the Sarah Connor Chronicles. He also stated that he would like to portray a gay character again in the future with full knowledge of that characters sexuality so he can give the character the kind of development and performance the character would deserve. 
- Thomas Dekker told SyFy Portal, "[Zach] was never intended to have any kind of importance in the story, but his presence just kept growing and growing."
- According to his MySpace page, Zach is a practicing Wiccan.
- Zach text messages using the handle FILMSBYZACH. (Homecoming)
- Zach's laptop is a Dell Inspiron 710m running the KDE desktop manager, which is most commonly used on Linux. (The Fix)
- According to his MySpace page, Zach's birthday is on March 15th.
- In the script for the unaired pilot, Zach's character was supposed to be an "artsy looking gawky" girl named Zoe.
- Zach drives a Nissan with Texas license plate "P55 JXH". (Distractions)
- In Strange Attractors, Claire explains to Gretchen that she is the first real friend that she's had since she moved from Texas. This seems to be a nod to her friendship with Zach, that disintegrated towards the end of Season One.
