I remember playing Fallout 3 for the first time and getting to the end with Fawkes as my companion, and getting extremely pissed that he refused going into project purity, no one needed to be sacrificed, he could simply turn it on with zero issues to himself, he knew that, he even offered to go into heavy radiation before to spare the player the extreme radiation.
But nope, at the end suddenly the player needed to die, the player who helped set him free.
Yeah, thanks for that...
Never understood why the player was shunned.
