Yes, there is no sign of anything specific or special about it at all in that cube. Practically Generic in every way. 

Of course it would be those fucking squares.

Because those squares are the literal computer building blocks for when an object is supposed to be there but isn’t.

Well at least Roxy managed to summon that.

Alright, so last we left Roxy is being forced to try and steal the Troll-Egg-Sack from space, Jade is threatening when she doesn’t talk, the kids are all split up on the planets, and John is just gone.

Not like….gone gone, but still gone. Which is concerning.
