Someone asking what he thinks, let alone his opinion--someone asking for his input--it's still new to him, and he blinks rapidly, almost owlishly as he watches the other for a few moments, as if seeing if this is some sort of test.

It isn't, he knows, but it's a knee jerk reaction. Had he said something silly? A poor observation? No, that's not it. It's only after his mind circles different possibilities and comes to a blank that it occurs to him that Sam really is asking for his input.

He chooses his words carefully, next. He picks up a smooth stone and rubs it with his thumb, enjoying the soft texture on his hand.

"I think" his voice is bashful, "I think this was purgatory, sir." It seems foolish, now that he's said it out loud--like a childish sort of whimsy--and Credence lowers his chin, physically retreating into himself.
