The pilot script describes Lydia as "a drop-dead gorgeous junior ... who strolls the walkway like it was a fashion show runway in Milan." In her callback, Roden asked to make the character more of a brainiac. "I thought about Tracy Flick, from Election. I wanted to put more of an Alexander Payne slant on things, where she's a bit quirky and a bit too studious for her own good. If you look at her, she's not really surrounded by a lot of friends, per se. She's just sort of in her own world."
The show clicked with teens in the post-Twilight, second-screen era, and the popularity helped Roden, then a relative unknown, amass roughly 6 million followers across Facebook, Instagram, and Twitter. MTV had asked its actors to join Instagram to help promote the show. Along with Pretty Little Liars, Teen Wolf became one of the first teen-oriented shows to capitalize on social media fan engagement. "I thought it was kind of pointless, but over time, I've obviously changed my mind on the topic," the actress admits. Roden currently has 3.8 million followers on Instagram -- that's almost 3 million more than Game of Thrones star Lena Headey and Seinfeld legend Julia Louis-Dreyfus. Instagram proved to be a secret weapon, a way for MTV to further plug premiere dates, fan contests, and fun times behind the scenes.
