Another take is that Lily really is just a doll, and Alexa’s twisted mind has unlocked a supernatural potential so great that she could easily demolish the tag-team champions and defend the titles on her own.
It’s certainly an unexpected direction for the WWE to take if Alexa does end up pursuing the tag titles with Lily, but an interesting one.
I won’t say if it’s a bad or good idea just yet, but I do appreciate the potential twist of the WWE giving Alexa a different route than the obvious path many expected if that’s what’s happening here.
