[...goodness lord, Mondo, can you warn a guy before just kind of materializing out of nowhere?

Ishimaru jumps a little, clearly not having expected anyone to actually walk in, as much as it may have looked like he was asking for it; he's still a bit tense once he realizes who it is, but it's really no more so than usual - it's pretty rare that he actually relaxes properly, anyway.]

Ah - just getting my thoughts in order, that's all!

[His tone is incredibly blunted, as usual, but he doesn't seem particularly nervous, nor does he see any reason to be abashed at it any; he shifts his grip on the chalk, toying with it between his fingers a little before he seems to realize what he's doing and makes himself stop.]

Did you need something...? I wasn't planning on staying here much longer!
