Before Liz Lee's stint as Louis' houseguest, she was living with her paisley tie-loving roommate in the dorms at Pratt Institute. They never really spent much time together, but we did see the "My Life As Liz" heroine extend a number of friendly advances (albeit unrequited) to her neighbor, Jeff.
Check out this bonus video from tonight's episode, where Liz confides in Jeff and tells him that she considers him a true friend. Jeff, on the other hand, isn't a fan of sappy moments and books it out of her room before she can do anything weird, like hug him.
