Final theories before the finale airs:
I think that blonde chick Dottie is really Arcana Jones (another witch from the comics). I think “Ralph” doesn’t really exist and was just a red herring. I think Evan Peters is really the X-men quicksilver (I don’t think they’d tease us by having him NOT really be him). I don’t think the aerospace engineer Monica talked about will be anyone special. I think vision and the kids will both survive. Lastly, I think the person in witness protection that Jimmy Woo was talking about is Dick Van Dyke (and this is the cameo Paul Bettany was talking about).
