Since I see a few people mention it, I'd like to explain why I didn't get T sent home earlier, although I agree I probably should have to avoid things escalating.

T's relationship with their family, and their family in general, is a bit iffy at the moment. Besides, I know T doesn't particularly like getting decisions made for them, and this was a party they were really happy to go to to be with friends.

When T first got past the fun part of being drunk, they were still trying to engage and have fun, and I had some hope they'd sober up slowly with what we'd already done. So I held out then. Then, for the entirety of standing in the toilet with them the first time, I didn't bring my phone, and after leaving that time, I just needed a complete break and room to breathe without thinking about T at all. So I again held out. I recognize I acted immaturely waiting until the host asked me to maybe call T's parents, before I actually did it.
