#2 She could adopt a persona similar to Finn Balor's Demon
Since leaving WWE TV, Liv Morgan has been posting cryptic Tweets indicating that she is in the process of discovering her real self. Most recently, Morgan Tweeted an image of a snake shedding its skin, hinting that the "real" Liv Morgan will soon be returning to WWE TV.
In addition to the above, Morgan has been teasing that she does not know whether or not she will be returning to main roster TV as a heel or a face.
If she can pull it off, it might be an interesting idea to see Liv Morgan play a character similar to that of Finn Balor's Demon, in which Morgan has a dual persona, one of which is a babyface and the other is a heel.
The character could be something similar to the demon, but more akin to Jekyll and Hyde, with Morgan constantly battling between which version of her is the "real" Liv Morgan.
