Throughout the past day or so, several odd things have been happening to Hayden MacMahon. First, his keys disappeared while he was at work last night, only to be left where only he would find him at the bar when he came in to Happy Endings for his shift today. When he comes back from his shift tonight, he'll find that many things in his apartment are out of place – a remote here, some dishes there, some clothes from his closet, etc. Most obviously, someone has been using his shower, though his towels are still dry – actually, no. Upon closer inspection, it's clear they've been freshly washed. If Hayden hasn't put together who the culprit is, he will by the time he takes a shower, because the steam from the hot water will reveal a message written on his mirror, as if the writer simply couldn't resist leaving a calling card:
LET ME IN.
Incidentally, it was Katya's day off today. She also ate some of his food.
