Have you been in a situation where you wanted to leave a place, but you don't want to leave the place...for certain reasons? That's exactly how Captain Wayne was feeling right now. He wanted to leave that spot 'cause he wasn't achieving what he came there for, and he didn't want to leave 'cause something crucial could come up.
He could later achieve why he was there, so he was just forcing himself to still stay there. He was still swinging his sword training, and Abner and his friends were still standing there discussing. After about two minutes more, the discussion wasn't about food anymore, this is what it was about,
"So, before the apocalypse broke out, who did you love more, your mum or your dad?". Abner threw a question to one of the guys close to him, an S class student.
