[After several close calls to slips and stumbles, L does indeed reach the small alcove. It's plenty big enough for him, and maybe for Heather, too, if she manages to get there as well. Not that he thinks that's a likely possibility; the creature has seen them, and if she were to hide here, it would defeat the purpose of "hiding". The creature could probably smash this little hollow with one blow.

He peers out the doorway, the static in his ear as he watches Heather bound toward the creature. He doesn't yet realize that he's holding his breath.]
