Eugene had been worried about his dad, but Arthur was actually more worried about Eugene. He also got abused by them, probably didn't even realize it until he was old enough.
Arthur looked at Eugene, carefully observing the omega's expression. "How do you feel? I know you're angry, but...are you scared too? Do you have any trauma?"
Eugene had been in such highly emotional states these days, so Arthur was worried it would affect the omega even more when he had to face the people who used to abuse him. He still remembered Eugene's story about how his brothers were locking him inside a shed to 'turn him into an alpha' in the past.
"No."
Thankfully, when it came to himself, Eugene was stronger mentally. He even scoffed at the notion of being scared of them.
