[John gets notice that he's received a link, and flips open his own journal, squinting his eyes at the screen until he finds it. Not too technology prone, this one. As he skims through the information, his shoulders (unmarked and scarred alike) relax just slightly and he looks up at Loki with a tired but appreciative look.]

Thank you, this'll help a lot.

[As the god talks, John frowns once again, glancing between the information in front of him and the man speaking. When he finishes, the doctor lets out a slightly bemused breath.]

A friend of mine probably would have said something similar...

[He clears his throat and nods curtly, military.]

I'm sure you're right. We can't know for sure what's impossible if the rest of this place is able to exist in general, let alone the limb additions. There must be something we're not seeing, or maybe even able to understand at the moment.

[With that, John closes the journal, his wings flexing in barely contained energy.]
