[Charles almost laughs, but doesn’t quite. Which stings more than it should. The mention of sentinels, even in noting their absence, makes him tense and the sting is forgotten. The deep well of power that he tasted when at Apocalypse’s side, so vast and deep he could have drowned in it, was gone. But left in its wake was the realization that his own abilities were far greater than he had realized. There is some comfort in that, at least. His hands flex, long fingers curling and uncurling, though not quite tightening into fists, or tensing as he directs the flow of his power. Not yet.]

If sentinels should reveal themselves, they will find it difficult to accomplish much.

[No arrogance in that, for once. Just the solid assurance that there is no man-made metal object that he cannot conquer. Charles turns toward the pyramids, and Erik hesitates just a moment before following. What is it about them that disturbs him so much? They inspire a feeling of dread he cannot name or shake.

Foolish.]

Multiverse. [A theory he had encountered, though one he hardly understood. His preferred area of physics was of the particle variety, not the quantum. He is certain that Charles does not know much more than he does about it, although if he was interested he could quickly master it.] I don’t suppose we’re lucky enough to be joined by somebody who has more expertise in that field than we do.

[Closer now, he realizes that Charles is not actually wearing a wig. Does that mean he is from a different… multiverse?

There’s more than one Charles?]

When you say we're not the only ones do you mean... Am I going to meet my doppleganger?
