This is a spoiler warning!
Well aren't we a merciful bunch. When Epic Games asked us to decide whether the third (and only remaining) Carmine brother would live or die, we voted live, and so he did. Even so, Epic's decided to sate our morbid curiosity by showing us what would have happened if we had been less merciful.
The last two brothers weren't as fortunate, as they both meant grizly ends at Locust hands on the battlefield. At least Clayton would have gone out peaceful-like, though we can't help but wonder why Carmine is bathing with his pants on. The fart at the end, by the way, is a classy touch.
