You're right! But the aunt didn't do anything to him, he happened to hear something she was mentioning to his mother, that given the circumstances (what happened right before he heard that), made him feel shameful and dirty. His aunt was being a shitass, but she never said anything directly to him, and although what she said was icky, his young mind made it way worse than it actually was and it traumatised him.

I’m probably like hella wrong abt this but the whole situation w the aunt reminded me of the perks of being a wallflower… what if his ed has something to do with his trauma regarding… his aunt or sum idk, he didn’t seem to put off by her but you rlly never know (⊙…⊙ )
