[He doesn't even hear Takasugi approach, still panicking about the slime that has glue'd itself to his face and trying to breathe . . . when he feels the nick of Takasugi's sword on his cheek he panics more because what the hell is going on?! Is it eating his face?!!

Only to feel the slime slowly slide down his face and neck, making sure to make it all slimy as it splats to the floor of the lab. He'll turn his head and watch it cautiously, only to hear some some beeping by the door. A short - like really short - figure was huddled by the control panel in the dark room. Gintoki glances around again, noting the other piece of the slime - seems like this person helped him out. He'll stand up and get closer, sounding a little sheepish.]

Ahh, hahaha, these things are like, really persistent. I don't have any gold or EXP to give you but thanks for help. . .ing. . me ou--uhhhh-hccckkk. . .

[He'll pause, recognizing that figure immediately once he gets a better look, his thanks devolving into a choking, vaguely vomit-y sound.

. . . and then he'll wordlessly lay back down on the ground, picking up the slime on the floor and putting it back on his face. Kill him.]
