Lucky had still not made up his mind. He was split between seeking vengeance and attempting to forget the events of twelve years prior.
His mother would still be alive if it weren't for those hunters, and he wouldn't have lost out on all the motherly affection because of her absence. At the same time, pursuing retribution would result in a brutal conflict between the hunters and the phoenixes, which was the last thing he desired.
A blazing conflict between humanity and otherworldly beings.
"I-" He began, then halted, since he didn't know what to say... or rather, he did know what to say, but he was frightened of hurting his mother's feelings.
He wanted to make her happy and would go to any length to do so, but retribution against the hunters would be counterproductive because those people would never want to know who attacked them and who did not.
