Peter was relieved when the Doctor showed up, he was very obviously losing Irene the more he tried to explain and maybe a little help with the matter would go a long way to reassure her that he wasn't quite as crazy as the premise of this place made him seem. "Doctor," Peter greeted her and nodded when she came around to the idea that she was just going to have water rather than a drink, he had a feeling that was probably for the best right then, "I'll get that for you."
"X-Men," Peter corrected gently, but honestly had a feeling this was probably a conversation better served by leaving it to one of them or the other, rather than bouncing back and forth between the understandings that they both had of the multiverse and what that meant for this place.
He slid the glass of water to the doctor though. "I was doing my best, I think the Doctor might be a little bit better at explaining what we're dealing with though." He allowed, because his gestures were well and good but he knew he was just giving out the most basic explanation.
