Marcus was definitely tired of seeing and watching you die mostly..2-5 days a week. But he's used to it unlike before where he first saw you die in a gruesome and painful way possible. He's used to it since he always saw you die in random ways in a random place. Like the time on where you got hit by an arrow in a park, got attacked by a bear while camping and even when a man accidentally threw his knife on a wrong target and ended up hitting you. He always does tried protecting you but he gives up and just watches what happens since he knows that you will be reborn and be alive again tomorrow looking like nothing's wrong is fcking happening. He knows that it's a curse since he can't imagine the pain of always dying and next day being alive again and again.
