2. Velveteen Dream
Of all the options discussed orbiting this story, the one conveniently absent is Velveteen Dream. While the likes of Ciampa and Undisputed ERA are perfect candidates for such an attack, Dream is an oddly fitting choice. Sure he is off to an intriguing face turn (if it is deemed that) but it feels more of a character alignment to the narrative with Ciampa.
Remember of all the individuals involved, Dream has the greatest narrative with Black. It was Dream's perverse pursuit of Black, that put the young man on the NXT radar. It was also there when beaten by Black that Dream found a form of validation. Dream lives for the adulation and fan response might be high, but the passion spewed forth from Black's mouth when he named Dream could be enough.
It's what Velveteen may seek en route to trying to capture NXT gold. He wants Black all to himself. It's a twisted Batman-Joker style narrative that places two of the most eccentric characters at the centre of the championship quest. Velveteen Dream loves Aleister Black and if Black will continue just feeding him scraps, then Dream's going to the whole hog to have the whole meal. The best way, get Black's attention to an escalating point of volcanic erupting rage.
