He’s a kind, soft spoken old guy who just wants to see the best in people and keep a sense of justice in an already messed up world. Even after all the cruelty he’s faced and the sheer mental trauma of waking up after the Apocalypse in a trash-heap; only to realize his minds a copy and the Nick Valentine who was a cop and had a fiance named Jenifer Lands wasn’t technically him.
I mean he said himself he was scared, confused and ‘mad as hell’ when he first woke up. Who wouldn’t be? And this was after years and years of being the institutes lab rat, honestly having most of those memories stripped was probably for the best. But just being shown a scrap of human
kindness by a group of settlers was enough for Nick to still believe
there was something to hang on to, and not to let his situation drive him to become something like Kellogg was.
So yeah when I do something bad and this amazing man shows disappointment you bet I feel like crap.
