It was interesting to see them tease an appearance of Brock Lesnar, then not only fail to deliver on it, but to then break the fourth wall by having Roman Reigns head straight to the Gorilla Position to confront Vince McMahon about it (with Shane McMahon clearly being there too).
Just as interesting and certainly unexpected was John Cena doing "what he wasn't supposed to do" and challenging The Undertaker for a match at WrestleMania, continuing with the line-blurring that Reigns started. Although I truly thought that last year was Undertaker's final match due to his actions afterwards, there is obviously no way that Cena would be able to get away with the challenge and his comments - especially without his microphone being cut off - if it wasn't really being put together to happen.
As a result, I can only assume that this year at WrestleMania, facing John Cena, will be the actual final match of The Undertaker.
Asuka choosing Charlotte Flair to face at WrestleMania was surprising, especially as I thought that she had already made the decision to face Alexa Bliss, but without her specifically doing so on Raw unless I had missed it at some point. Alexa Bliss making her way out to interrupt Asuka's explanation of why she chose Flair had me wondering if Asuka was going to say that contrary to how it looked, she was challenging Bliss, and that furthermore, somehow she had chosen to face both champions at WrestleMania, perhaps in a Triple Threat match.
Such a match however would obviously mean a title unification, which is highly unlikely considering the fact that it hasn't been long enough for both titles existing (something which would also apply to the Universal Championship and WWE Championship too) to make sense to take such a step once again in anywhere near any time soon.
Even if it were to happen, it would surely be at least a few more years, but even then I doubt it as it would make it seem like WWE can't make up their mind if they keep merging and then separating championships to both brands every few years.
What is also clear however, is that what previously seemed to be an uneasy alliance between Alexa Bliss and Mickie James has now turned into a definitive heel turn for Mickie James, as shown with James' words and actions alongside Bliss' own.
I have to admit that when Braun Strowman appeared to enter the tag team battle royal, I half-expected (either before or after the match, but most likely after) that his tag team partner would be revealed as Alexa Bliss (his partner in "Team Little Big" on Mixed Match Challenge) for an even more unexpected Raw Tag Team Championship match at WrestleMania.
I of course realise that is still unlikely as the WWE probably wouldn't be comfortable with such a match given that it would obviously lack the matched gender requirement of a mixed tag team match on the part of Cesaro and Sheamus, plus it also seems clear from the earlier events involving Nia Jax that a WrestleMania match is being set up for Alexa Bliss facing Nia Jax for the Raw Women's Championship.
So of course this begs the question of who Strowman's tag team partner will be, even if I wouldn't really be surprised if he stayed as a one-man team and faced Cesaro and Sheamus for the Raw Tag Team Championship at WrestleMania, I'd still imagine that something else is actually in mind.
