People are tripping out at Julian Dennison's character in Deadpool after this video dropped!

It's probably been the best-kept secret in Deadpool 2, what is Julian Dennison's character in the film!

As a nation, it would be fair to say that we collectively lost our shit when Julian Dennison was snapped on Ryan Reynold's Instagram, riding his back whilst receiving an extremely nice compliment about his acting ability.

After seeing that exact picture we spent many a night trying to figure out who young Dennison could be playing! Captain America? Cable? Young Deadpool? So many questions and not much in the way of answers...until now. A behind-the-scenes video dropped and we've been treated to some first images of Dennison in character!

Okay, does anyone know who he's playing!
