Based on my theory, when Euler created infinite-dimensional sphere in the ending of AvMath, this formula teleported TSC to multiple, if not infinite amount of different dimensions at the same time, means it "cloned" him and now his copies exists in every dimension (for example we saw TSC from Physics appearing from a white sphere as from Math episode), and Orange from Geometry was another TSC than Physics one as we see in the ending, and this fourth-dimensional cube is natural process in these dimensions, which wants to get rid of Orange, because he's anomaly made by Euler which wasn't supposed to exist, and in the ending of AvGeom we see that there was multiple of this "hyper diamond" versions, so it might come back as different version in future episodes, with different form (it was a 4D shape in Geometry because it was made by this dimension rules, from shapes), for example in Animation vs Chemistry it may return as dangerous chemical substance, which would absorb various chemical compounds to become stronger, and it would be the main antagonist for AvE series, like Kang from Marvel to make it more clear
