[ Strange isn't an idiot. Childermass has been here for a while, he knows what's up, he's not going to literally run into a mirror the way Strange did. So, he lets Childermass drag him around, though he's got enough pride to shoot him a look that's pure "what the hell, don't be so rough."

And oh hey now, that's interesting. So not only was this place possibly odd with regards to it's own interior time, but with time in their world? Strange doesn't know if it's the madness or the magic that makes him sort out the pieces in a seemingly logical manner, but he does, and he can't help but fix Childermass with a smile as he comes to entirely the wrong conclusion. ]

Well, then I must have succeeded and fulfilled my contract! After all, I am here. But I must eventually go home in order to be back in England. And since I shan't break the contract between us and I won't leave until I find out that information, I must have gained what I came here to find, filled the terms of my contract, and returned back to our world.

[ THERE IS NO PROBLEM WITH THIS WHATSOEVER, four for you Strange, you've got this figured out, give it up for your arrogance. Though he doesn't have one thing figured out, though... ]

But that doesn't explain why on Earth I'm back in England.
