#2 We will see a lot more change in Alexa Bliss in the weeks that follow
When one undergoes a change in character, it necessitates the person to make significant changes to her/his persona, and one has to believe that we will see a lot more changes in Alexa Bliss in the weeks that follow.
Yes, Alexa Bliss has a new look after eating the Mandible Claw from The Fiend not very long ago, but one has to imagine that she will get new music as well (Imagine the Monday Night Messiah coming out to 'Burn it Down', for example, or even Bayley coming out to her former theme song, at this stage). And even in terms of her look, now that Alexa Bliss has embraced the darker side of her persona, could we see some significant changes?
Maybe she starts wearing the Hurt/Heal gloves, going forward.
One thing is for sure, that in a few weeks, while she embraces this transformation, Alexa Bliss will be a very different person from her bubbly NXT character or even her whole 'Goddess' persona.
