I was rereading old posts, and I saw a reference to a bit of dialog that was in a trailer, but not in Legacy? Certainly, I've seen that happen before with other movies. I believe it was indicated to be dialog from Alan to Sam in reference to telling Sam if he learned anything about his father? I'm not sure, as the post expected the reader to already be familiar with the content. However, if there are any bits like that - not in the movie - could someone maybe tell me what they are and point me in the direction of the relevant promo(s)?

I'm not including the test footage, of course.
