So. In this issue Charles kinda lost his control while he’s still connected to Cerebro and he makes all the kids go into his mind like a leaving dream. They start by morning like everything is just fine, Charles is able to walk, they have the old Chef of the Xaviers cooking to them (and she’s actually dead), Scott doesn’t need his glasses etc. Everything seems so perfect and good. All of this is happening in Charles mind. And Jean kinda of notices there’s something wrong going on and she and Scott go check it out.
And there’s Charles living his dream: playing chess with Erik. Erik without the helmet. They drinking some wine.
In next scene Erik is asking to Jean and Scott get out and let them play~~.
Note: int he next scene, Charles tells Magneto ‘Okay, this one’s for the helmet’, which suggests they are actually playing strip chess.
