Makarov missed. when attempting to kill Soap, his hand slipped, and he shot a nonlethal part of Soap's brain. as a result, he was in a coma for several weeks, but woke up, alive and well. though, he wasn't really Soap. he is suffering from retrograde amnesia, which means he doesn't remember anything from before he was shot.

He was discharged from TF 141, and he is living off of money higher-ups are sending him through legally necessary checks. he doesn't remember you, or anyone he used to work with, he doesn't even remember his own mother. the whole thing was heart-tearing, Soap might as well be dead, the still-alive shell of the man he used to be is almost too much to even look at.

Yet, here you stand, at his front door, with his dog tags in your hands.
