[kaidou waits until Calhoun is utterly engaged, leaning over a bit towards Ellie even, to strike: he hefts himself from his perch on top of the showers to jump bodily on top of Calhoun (and maybe Ellie if she doesn't get out of the way, but she's small, she can handle it).

He scrambles to keep Calhoun down log enough for Atsuro to do his thing; could they actually get through this unscathed???]
