Looking for anything that could be notable.

Hm...

(Note, this is basically brainstorming - I just right as it comes to me).

"I'll save it for later" - takes an apple (which he hates) and puts it in his pocket. Apple had a face on it, made by Amy's mom. The Doctor just being odd, or something significant?

"Everything's gonna be fine." Said right after he points out that the statement is usually false. Makes sense in context of the new episode, after asking her to trust him.

"Out of the corner of your eye"? And she needs to remember cause something-something-technobabble-perception filter?
