Curate, connect, and discover
Something interesting I noticed in AVA 2 is how TCO is immediately aggressive towards Alan. A theory I have for this is that the original victim was reincarnated into TCO when the file wasn't saved.
In AVA 1, the original victim surprisingly does not use the lasso as his primary weapon, he instead uses the shuriken. The fact that in the box victim prefers using the lasso above any other weapon leads me to believe he is the clone which used the lasso in the first AVA.
Another piece evidence supporting this is victim's strange appearance change from AVA 1 to AVA season 3. Mabye clones start to slowly corrupt the longer they are not absorbed into the pencil, even to the point of changing their colour?
TCO also seems strangely reluctant to fight victim in the box, instead trying to diffuse the situation. It's possible that TCO may recognize victim as one of his clones.
