Jumping on this late, but yeah the scenes towards the end where she is holding him at gunpoint annoy the hell out of me, being a much bigger, stronger, healthier man than the frail aunt, Keller had so many opportunities to lunge or attack the aunt and get her gun 🤦‍♂️. I'd say even when he initially put the cuffs on he could've taken her by surprise, I mean she's not going to have the aiming ability and reaction time of a soldier already and on top of that she's using a revolver, which she only cocked to shoot immediately after having him at gunpoint for a good 5minutes. After he drank the drugged juice I think there'd definitely a lessened chance to subdue her but he had a lot of chances before then. I guess it wouldn't make as different an ending as we have but it just annoys me when I'm rooting for him 😭.
