tadc but i point out details || tadc commentary 

A Hatchetfield Trilogy PLUS a TADC fan???? Same :D!!

Since you pointed out the possible Caine and Abel reference, maybe Abel is Bubble since their names sound very similar. Also, if you look at the doors when Pomni, Ragatha, and Jax are walking down the hallway w/ all the rooms, you can see another chess piece character. That character could possibly be related to Kinger. Also also, since Gangle has both a comedy and tragedy mask and her comedy mask keeps breaking, maybe Gangle's IRL form suffered from depression and played (?) the Digital Circus to get away from her problems or the reality of her world.
