If Foster were hoping to avoid Strange's energy, to keep his own notoriously unreliable sanity in check, he's doing a terrible job. The truth is that Foster is often just escalation in human form--Strange's insistence on locking eyes with him is less "deer in the headlights" and more "setting the water to boil."

Or maybe more like setting the water back over the fire. Either way, he'll find that same kind of glint--just deeper in, and maybe a little bit darker. If it makes any sense at all for a light to be darker.

"Tell me about your world," Foster says--he's still holding his head up, as though attempting to look over and then down at Strange, instead of his usual worm's-eye angle. It's still eager, though, his eyes partially lidded but bright with unconcealed interest.

"Then the Carnival."
