"I didn't lose it, that fiend stole it from me." This provides absolutely no context whatsoever, but Strange is glowering like this is a huge crime and OBVIOUSLY Sora should be empathizing with him about this. He turns back to Sora, as if to say something...before noticing the umbrella. Ah. He's probably still a vampire.

"I can make it more cloudy, if you wish." It's just said completely out of nowhere, but Strange at least gestures to the umbrella for explanation. Granted, he wouldn't be able to remove the sun entirely, but a little more cloud cover might be good for the kid.
