Exactly! They tell you right off the bat that he doesn’t like small/cramped spaces and especially small cramped DARK places. He points out that he hates caves long before and he’s making it clear that he knows he HAS to go through these with you because he’s not going to abandon you even though he knows you could handle yourself in them, he walks with you anyways! And then when you’re both stuck in the cave in Aurora his PTSD symptoms go into full swing to the point it’s meant to panic the player with “We need the light!” And “we can’t get out!” then when the Crawler is trying to attack you both in the desert Walter’s inner thoughts STRAIGHT UP TELL YOU HE ALMOST DIED TRAPPED INSIDE A CAVE IN! He was running out of air in a cramped dark small section of a cave and watched his friends/comrades die first one by one yet HE managed to make it out and outlast them. Not only would that be horrifically traumatic if he was alone in general, but watching your fellow soldiers who you’ve become friends with drop like flies from starvation/lack of water/lack of air slowly but surely only for you to just make it out? Yeah HES GONNA BE FUCKED UP ABOUT IT AND HE HAS EVERY RIGHT TO BE!
