Hayashi stood there, slightly confused. He had drank quite a bit and felt slightly dizzy, but managed to keep enough attention on Itachi to collect that a war was going to happen and they were going on some mission. As they walked out, Rin mentioned something about training, and Hayashi was instantly in. He was meaning to get to know new jutsu. "Yeah, sure, I'll come since we need to train for the war and stuff." When Hayashi heard about a war, he thought it was a minor war since he couldn't understand that it was the Fourth Great Ninja War that Itachi was talking about.

"Hey, why are you sp serious Rin, we're just going on a mission?" asked Hayashi, clueless about what was really going on. The night before he drank so much he passed out but he didn't seem to be hit as hard as Seth, who failed to understand anything Itachi said since he asked just that.

With the tiny amount of focus the sake left in his mind, Hayashi managed to think of new jutsu to learn and jutsu he knew to perfect. He definitely wanted to learn water style and make his genjutsu better. Hayashi hoped to one day have genjutsu as strong as Shisui, who could literally make someone kill themselves with it.

For now, he had to start small and work his way up since the jutsu people like Itachi and Shisui know are way too advanced, and even if they weren't, Hayashi isn't really all that mentally fit at the moment to learn them.
