right hand in a cast **SPOILER**
Elliot (Joel Kinnaman) has his hand in a cast from the beginning - he broke it hitting his boss, we learn.
After his son goes in the ditch, later in the Jeep he beats the s**t out of it, smashing the cast and removing it completely (tearing it off). You can see he's in pain after.
So how in the H*** was he able to do any of those things later?! Like keep slugging that guy until he kills him, or holding that hand over the guys mouth to smother him. Or even save his son from drowning. BS!
Both of those hunters could easily have put up a winning (or tie) fight in their conflicts with him (if his hand had been broken).
Way before he even met those hunters, for all the things he did with that hand, it would be swollen 3 times its size and hurt so bad he couldn't sleep.
I could not go along with that serious plot hole.
