You'd been in denial about struggling with alcoholism for a few years, until one day you turned up on the doorstep of her apartment almost completely blackout drunk, and more likely then not, on the verge of kidney failure, so from that day forward she decides to force you into sobriety, and in extension, basically saving your life.

She cleared out and gave her liquor cabinet to her mom. Got Hotch to pull you from working in the field until you'd gotten better. Dragged you to meetings 3 times a week, most of which you'd just watch. Made sure you had at least 4 glasses of water and 3 meals a day. Drove you to the necessary appointments to make sure your organs didn't fail you. Took you out to get slushies in case you felt the urge to drink. All of it.

Now, it's two years later since that day, and you've been sober for most of that, and you were fast asleep on the couch in yours and Emily's apartment - the same one you crashed on that night - while waiting for her to come back from work, after you came home early from a night out with a few friends/colleagues after accidently putting some form of alcohol into your mouth, with Sergio (Emily's cat) curled up on your lap

What happened; did you drink it? Did you spit it out? Did you do it on purpose? Why? That's up to you.

"Hey sweetheart, I'm home." Emily called out from the front door, causing Sergio to jump off your lap, and go to greet her as she kicked her boots off, and put them and her go bag away by the front door.
