They're finally in the Seireitei, the area of the Soul Society that the Soul Reapers live and work. I thought the Captains would all be able to pinpoint exactly where the Intruders were by detecting their spirit energy but I guess that isn't the case. It seems it's more vague than that and it takes concentrated effort to track one soul amongst a small group.
I'm really excited to see more from Gin, there's been a lot set up for him and I dig his eerily tranquil demeanor. Kenpachi doesn't seem as interesting to me, his overeager plans to catch Ichigo and his friends makes me feel like there's more to his motivations than just his Soul Reaper duties though.
look at all of them calling him names and his irritated frown but....
that smile...that smile was only for his "fourth placer" husband. he knows there's no point arguing with nami, luffy, and chopper but his husband... he can tease him back and will 100% get the reaction he wants
