Hmmmm. Shima doesn't know enough about corvids to really get the nuance of that hesitation, but it's enough to at least tell Strange is holding something back. So he sidles forward a little, head bowed to kind of jab/nip bluntly at the raven's chest, a rude but playful gesture that also puts himself in pecking reach. He's only a little bigger than a house cat though, and most of him is fluff, so it won't knock Strange over or anything and he doesn't yank any feathers.

"Well, that's true. But you're sure keeping things pretty close to your chest too, aren't ya. C'mon, how's he actually doing? Did ya or didn't ya ask what he saw? I'm trying ta be helpful to ya as much as I can, ya know? Don't hold back~"
