You know, I think I could have run with this psychosis angle. Plus, Felicity was acting fairly crazy when she call Ben in the middle of the night to tell him that Zoe with in the hospital with her. She totally could have pulled it off.
But anyway, desperate to try to continue dating Noel, she tells him she traveled back in time so they could be together. Needless to say, he thinks she's crazy. He goes and tells Ben about it, but he doesn't believe it. So, he goes to see Felicity for himself. And he walks in just as she trying to make a potion to send herself back.
After that, the two of them team up and have her talk to a psychiatrist where she's admitted to a hospital for observation. However, in the hospital, she runs into Zoe (who has no idea who she is), but this convinces her that she isn't crazy.
The next day, Lauren calls Ben to tell him about his dad, and Ben realizes that Felicity has been telling the truth. So, he heads down the hospital to break her out. While they are talking Noel calls and tries to convince her to go back, but then he needs to hang up abruptly due to the fire (you know, the one he was just find from in the future).
Felicity and Ben talk some more about the future and Felicity tells him she came back to the past to be with Noel because Ben cheated on her. Ben convinces her that maybe she came back to fix things with him. So maybe she can stay in the past and not go back to the future.
Meanwhile, Meghan goes out of her way to make Sean look stupid, and while returning something she discovers that the account on file is the name of the witch whole book hasn't yet been written to send Felicity home. (That was a hell of a sentence).
After she doesn't hear back from Noel she gets nervous and checks her machine where she has a message from a police officer. When she calls back she finds out that Noel has died in the fire.
