Heroes

The license plate on Kaito Nakamura's car is NCC-1701. George Takei, who plays Kaito, was Mr. Sulu in the original incarnation of Star Trek (1966) and NCC-1701 is the registry number of the U.S.S. Enterprise.

Throughout all four seasons, Claire is often shown wearing earrings without an explanation addressing her healing ability preventing her from having pierced ears. When Claire's ability manifested, she could have begun to wear clip-on earrings, but this is never mentioned.

It could also be explained by her getting her ears pierced before her powers manifested. Her power might only work to restore her to the state just before an injury, as well as what even constitutes "injury." The piercings would have already healed and thus not seen as an injury, much like she wouldn't stay the same age, her body wouldn't return that of a baby, etc.
