Sage is not dying, she has a flu, and she lives in a house full of people, there is absolutely no urgency.
If you're interested in Jill, go with her, if not, you can do as you please.
Slapping Tybalt is not self-defense, it's an act that if you're interested in Jill you know she won't appreciate, but again if you'd rather put your hands on Tybalt

you are free to do so.
The point isn't that you can't choose differently, but if you're interested in Jill it's clear what you should choose, if you don't you can't talk about weird consequences
From the blackmail onwards Jill's story is ridiculous, so it's perfectly fine not to be interested in her.
