As Alexander cleaned his armor off with Senna standing guard, nothing seemed to happen. It appeared that there weren't any approaching monsters; maybe those three Goblins and two Slimes were the entirety of this floor's monsters? Only heading further into the tunnel of the first floor would tell for sure. 

Incidentally, Alexander's efforts to wipe off the slime would be largely successful, enough that it wouldn't affect his movement much when dried, but for a complete job he'd need some water.

You know, while those two are standing around here, now would be a good time for other people to show up.
