'Breaking Bad': Mike's Quiet Exit (Season Five, Episode Seven)
In the end, he goes peacefully. Okay, sure, he has to tell his murderer to shut the fuck up in order to make it happen. But still, for Breaking Bad's Mike Ehrmentraut – fixer, enforcer, doting grandfather, cold-blooded killer and ersatz partner to Walter "Heisenberg" White – quietly tipping over into oblivion while sitting in the reeds and watching a river flow past in the sunlight is probably the most tranquility his murderous life has afforded him in a long time. Pity he earned these final moments of rest by getting shot in the gut because he hurt Walter White's feefees.
