Well I mean there's not much to do when you're stuck inside a tree, so after a good five minutes of attempting to use magic to force himself out and another good five minutes of trying to scream himself hoarse in the hope that someone could hear him, Strange just resigns himself to leaning against the inside of the tree and just thinking of all the ways he could possibly get himself out of this mess (and then realizing that a lot of those ways revolve around his proper magic which wait a moment, he doesn't fricken have.)

Hopefully Nightshade remembered that people need to do things like 'eat' if she ends up taking a while.
