After the werewolf that bit Claire talks to her about how turning is a good thing, Claire calls him "Teen Wolf". This is a reference to the popular MTV show of the same name,
Teen Wolf (2011), based off of the
Michael J. Fox movie,
Teen Wolf (1985), about a teenage werewolf. An iconic line of a character from Teen Wolf, called Derek Hale, is the phrase "The bite is a gift," which is what the werewolf in this episode was trying to get across, explaining Claire's comparison.
