- The regeneration video Claire, West, and Martha watch in Mr. Zern's biology class is a real educational video to which the show obtained the rights.
- The set for Bob's office was built by Ruth Ammon and the production department. Greg Grunberg says he has shot a scene as Matt Parkman in the set.
- To make sure the actions in Caitlin and Peter's first scene match without burdening the actors with remembering their exact moves, all three cameras--the master and each close-up--were filmed simultaneously.
- Allan Arkush refers to Peter's electrical ability as "lightning".

- The scene between Hiro and Yaeko amid the cherry blossoms and deer is based on an experience Michael Green had during the hiatus while vacationing in Japan with his girlfriend.

- The commentary is filmed inside the set for the NYPD station.
- The commentators discuss Maya and Alejandro's powers in very general terms: Maya cries "black tears", and Alejandro "heals" their effects. According to Michael Green, "she emits this, and he can take it in".
- The special effects for Maya's black tears are a "nightmare". "Black goo" is squeezed into Dania Ramírez's eyes. As she cries, the tears begin to run and flow. The "black goo" is difficult to remove, and after a few takes, Dania's face is red from having been scrubbed clean.
- Alejandro's lullaby he uses to calm Maya is a song they used to sing as children. In reality, the song was composed in one day by Wendy and Lisa, and is based on a lullaby Lisa's grandmother used to sing to her.
- Copy Kingdom is filmed in Los Angeles, at Sunset Boulevard and Gower Street.

- Derek's back story--that he was on Spring Break, and was arrested for drunk and disorderly conduct--was written, but cut.
- J.J. Philbin confirms that Derek's car is Claire's stolen Nissan Rogue. Zachary Quinto says he has filmed upcoming scenes featuring "that car"; it's not explicitly clear whether he means Claire's car or another Nissan Rogue.
- While the commentary was filming, a piano was being tuned in the next set for an upcoming scene featuring Noah Gray-Cabey.
- The "ninety angry ronin" were originally "ninety hungry ronin".

- According to Adrian Pasdar, the cast and crew had several vulgar variations for what "HRG" stood for.
- Tim Kring talks a great deal about this season's focus on pairing up new sets of characters.

- There is a water line about three feet high in the set of the Dawsons' home to show the extent of the damage it received during Hurricane Katrina.

- Dana Davis's first scene filmed was her tomato-cutting scene with Camille. The scene was shot in an actual fast food chili restaurant in Los Angeles, redressed as Burger Bonanza.

- Tim Kring explains Maya's ability as the "emitting of a plague ... that makes people sick."
- The "Tim Sale font" used for all of the title cards actually predates Heroes.
- The commentary is filmed in the set for Bob's office. According to Greg Beeman, Bob is now "in charge" of the Company.
- Beeman calls Monica's power "photo reflex muscle memory power". Grunberg calls her "Xerox girl".
- Bob's office contains a didgeridoo. Beeman claims Bob has spent a lot of time in Australia.
- Monica's mother appears (very briefly) in a photograph on the top of the piano. Curiously, Greg Grunberg begins to comment on the chemistry between Dana Davis and the actress who plays her mother, but catches himself.
- According to Greg Grunberg, the set for Bob's office contains files for all of the evolved humans on the show. Some of the actors like to frequent the set because it's the only location that lists a last name for some characters, such as Bob (who is listed as "Robert Bishop".) However, Greg is quick to point out that the last names in question were selected by the props department as set dressing and may not reflect the actual direction the show takes.
- Greg Beeman confirms that Niki has the Shanti virus.
- Greg Grunberg discusses a deleted scene from late in Season One where Matt spoke with Janice on the phone and realized the baby was not his. Tom McHenry appeared in the scene, packing Janice's bags. However, the scene was ultimately scrapped because it took away from the dramatic tension and action of the last few episodes of the season.
- The martial arts move Monica practices is a kippup. The film from which she learns it is The Bruce Lee Story starring Jason Scott Lee.
- Greg Grunberg says he has a flying scene coming up in Episode 10.
- The combination of Greg Grunberg and Greg Beeman is perhaps best described as "comedy dynamite". The best line of the commentary occurs during Elle's phone call to her father:
- Greg Beeman: Now, I wanted a right-hand drive car...
- Greg Grunberg: ... but Nissan didn't make one.
- The car in question didn't actually work. When Elle drives off, it's being pushed by crew members.
- Intriguingly, Greg Grunberg implies that Matt Parkman will learn how to kill Peter in spite of all his powers.
- The commentary is filmed on the set of Charles Deveaux's rooftop.
- The initial scenes of Peter and Caitlin in the future from The Line were originally shot for this episode.
- Masi Oka claims that the material used for the opium was "medicinal or herbal", but that as a non-smoker he found it quite uncomfortable nonetheless.
- The shots of Claire's cell phone were edited using CGI to eliminate the date and time.
- The scenes at the CDC building were shot in the parking lot at NBC (for the showers) and at an abandoned industrial building in downtown Long Beach (for the processing center).
- Due to time constraints, the scene with Claire and West as Noah returns home was shot as a single, continuous shot and cut together, rather than shooting each shot individually.
- Shots of Maury Parkman were inserted into Niki's nightmare scene with D.L. to help establish Maury's power.
- The original plan was to have Mohinder inject Niki with the Shanti virus. The storyline was changed to be more consistent with Mohinder's objections to injecting Monica in The Line.
- The explosion in Whitebeard's camp was shot in one take. The explosion blew out the power, and debris from the blast flew into the cast and crew's tents.
- The scenes with Matt, Maury, and Molly inside the nightmare was shot during a set visit from the heads of NBC and Universal.
- The goodbye scene between Hiro and Yaeko was filmed after the principal shooting for the episode was complete. They were directed by Greg Beeman because Daniel Attias was not available.

- New scenes of Hiro watching Angela and Kaito's meeting were intercut with existing coverage of the scene from Four Months Later....
- As Noah Bennet prepares to search for West, he puts on his jacket and stops for a beat. According to Greg, Jack Coleman observed that if he were Noah, he'd be hesitant to put on a jacket in which he's been painted dead. This led to this small moment, meant to show Noah's acceptance of his impending fate.
- Elle is drinking from a Slusho cup, a nod to Alias inserted by Jesse Alexander.
- When Noah ties Elle up and sticks her feet in the dog bath, she is tied up with dog leashes.
- The scene with Kaito and Adam frozen in mid-air was achieved by building a support rig for the actors. The supports were edited out later.
