From Meryl
I think it backfired, though, because Ennis got even more alarmed when Jack didn't tell him his fears were groundless. By suggesting he move he was, in a way, suggesting that maybe Ennis was right and people did "know." Ennis probably blew up at him partly to cover that fear.
This absolutely is my interpretation of that scene.
Not knowing that she saw them kissing, Ennis thinks he's made a slip-up that made Alma see through him. And if she could do it, perhaps everyone can, - and he's been fooling himself that he's fooling them? So he's frightened enough to actually confide something personal to Jack, deep down hoping Jack will set him straigth (pardon the pun) and tell him that his fears are utterly groundless.
"Pffft- nobody knows, noone suspects, Ennis, you're seeing spooks!"But instead Jack's suggestion that Ennis move somewhere else in my opinion is understood by Ennis as
"Well, if that is so, maybe you should move somewhere else far away where people don't know about it". I think Ennis's facial expression immediately after Jack's line says it all - Jack's reply shocks and frightens him - though he's reining it in as usual.
(Tell me again just WHY Heath Ledger didn't get that Oscar, BAFTA, and so forth?
I still for the life of me can't understand it. )
Jack *did* miss an opportunity there, but - oh, as always in BBM - once more how realistically human his response is! He's been wanting and hoping, providing comfort, handling Ennis's skittish side, holding back....and more & more losing hope, and here's a chance that his wish to at least have Ennis nearer and to see him more often could in fact be presented to Ennis as common sense rather than a Jackish-flight-of- fancy. So he *pounces* on the opportuniy - and achieves only fuelling Ennis's fears.
Hm, lines with double meanings, here's another one which is pretty obvious, the way it's acted and all:
You forgettin' somethin'?- You're forgetting your fishing gear
- You're forgetting kissing me goodbye
- You're completely forgetting and disregarding *me*
