When Lyle and Sandra return home, they find Claire, still traumatized by her recent visit from Sylar. Meredith Gordon shows up to protect the family, and demonstrates her pyrokinesis by lighting her cigarette at the kitchen table. This disturbs Lyle and he asks his mother for help. A few days later, when Sandra and Claire return from fighting Eric Doyle, they find Lyle unconscious on the floor. He awakens and tells them that the "bitch is back". Elle attacks Claire but is stopped when Lyle throws a bucket of water onto her.
Two months later, Lyle sits and has breakfast with his family. He asks Noah about his new job as a consultant and fakes interest with a nod. When Alex Woolsly needs a fake ID, Sandra takes Lyle's drivers license, using the excuse that it is a punishment because he got a C- on his report card. After Claire goes on the run, Lyle is left at home to take care of Mr. Muggles. He phones Sandra while she is in Washington and makes Noah realize that the woman he is with is actually Sandra.
