After Eisen, Bree and Sal had returned to where the others were waiting for them, instead of going out to hunt immediately, they made the decision to sleep first so that they could hunt as long as possible after that.
Since Eisen wasn't really all that tired just yet, he didn't need to sleep that much and soon woke back up in the early morning time, where he quickly noticed that there were three people speaking right behind him.
He had been leaning up against Cabarum as he laid down as well, so it seemed like they simply didn't see that his sleep-transformation wore off.
"Yeah, he's been acting a lot different lately..." Sky said quietly, and next, Kirisho's voice could be heard as she agreed. "Eisen is just quite angry, or rather frustrated lately, is he not?" She asked, and it seemed like even Bree had to agree.
