I have a bold prediction for SS that isn't especially based on anything more than a gut feeling and fantasy booking, but I would like to share it anyway.

I believe that Carmella is going to cash in her Money in the Bank contract at Survivor Series... On Alexa Bliss.

Hear me out. It's been quite a while since the Superstar Shake-up, and Vince said he wanted to do two a year. If Carmella cashes in on Alexa, that's as good of an excuse as any to switch up the rosters. There's nothing explicitly stating that Carmella can't cash in on the other brand's champ (and, even if there is, I'm sure it can be easily talked away). Furthermore, Carmella is an intelligent champ, so she would cash in on someone who wouldn't expect her.

Anyway, that's just my thoughts.
