In one of Rue's narrations after Lexi's encounter with Cal in that same episode, she says that Lexi hated herself for being so passive and afraid, so she decides to say something. While we don't know exactly what Lexi wanted to say, we have an idea when she confidently goes to Fez's shop. She nervously fixes her hair before walking in and when she does, he absolutely lights up. However, her confidence quickly fades as she sees Faye sitting with Fez, assuming they're together. Fez, bless his heart, seems to miss Lexi's disappointment and attempts to talk to her as much as he can. He also offers an apology for not saying goodbye at the NYE party before they're interrupted by a vengeful Cal. We get to see little bits of hope and attraction between the two, but then something or someone gets in the way. This does not stop them from continuing to try though.
