Man at first I thought Francine West was gonna be a bad character. She probably still is ,but her background makes her pretty interesting. She was a drug addict that disappeared until now. Anyone else is thinking Wally West is going to be Earth 2 equivalent of Iris West? Maybe in Earth 2 Francine West/Joe West are abusive parents and as a result when Wally West becomes a speedster he does bad things. As far as I know there hasn't been any news to what part Wally West will play for the show. Maybe he is Zoom? The season finale of Season 1 where it shows Barry in prison makes me think there might be some plot twist. Just a theory. :)
Let me know what you think Francine West will do for the series.
