Vanessa Marano plays one of the leading roles on the ABC Family series “Switched at Birth,” which centers around two teen girls who discover they were, yes, switched at birth. But that’s not the most unique thing about the premise. In a big move towards visibility of deaf culture, most of the characters on the show are fluent in American Sign Language (ASL).

And, yes, Marano had to become fluent in it herself. “My character didn’t start signing until like episode six, which means [I] had to start signing around episode six,” Marano told Fusion’s Alicia Menendez. “We have someone called an ASL master who teaches us our lines on the weekends and that’s basically how I spend my weekend.”

But even if you’ve only casually watched “Switched at Birth,” you may well recognize Marano from a more infamous role – Luke’s daughter on “Gilmore Girls.” No, that role is not beloved by fans of the show.

Many believe her character was responsible for Luke and Lorelai’s breakup – and, these days, Marano can’t help but agree with the fans who blame her.

“I 100 percent feel I was responsible for the breakup. I was such a huge fan of the show and when the breakup came I was like, ‘Ugh, I hate her [but] I have to get this part, I want to be on the show so badly,” Marano said. “So I was in inner turmoil with playing that character.”
