OK, another session of skipping around the DVD in my now habitual cranked-volume, glued-to-screen, constantly rewinding posture. Here are my impressions:
"F me" -- I see where you're talking about, and he could be saying that, or any number of other things, or just breathing.
"Sorry/s'alright" -- I really like Daphne's interpretation of Jack saying "sorry." It seems to fit what's happening onscreen perfectly.
Holding hands -- Undoubtedly. Hands, not any other parts. For the record, I think it's Ennis who grabs Jack's hand.
"C'mere" -- Yes, said by Jack in TS2, and by Ennis at the reunion before and after the kiss.
Wedding ring -- barely a glimpse, but only because I've got a letterbox DVD.
"Oh, Jack" -- I saw the part where he tenderly touches the pocket, Daphne, but couldn't make out actual words.
"I love you" -- Absolutely. I become more sure of it with every viewing.
