Probably whoever is in gravest danger or, if the danger is percieved as equal, who physically closest to them at the time.

If one of you are able to save themselves they would save the other. If neither could save themselves they wouldn’t run past one of you to look for the other but get the first one they see out first.

I don’t think trying to figure out favourites like this is worth thinking about, past the sbive point. If you dwell on thoughts like this beyond a slight curiosity it might just be your mind trying to come up with different ways to hurt you and make you suffer emotionally. Don’t let it.

Let me introduce you to “I’m The Villain In My Own Story”: https://youtu.be/UhzN7SfnNeY

From the excellent (though sometimes emotionally heavy) show Crazy Ex-Girlfriend. It’s certainly not the best song in the show, but the most relevant.

And in the artery to that vein, let me present “I’m A Good Person”: https://youtu.be/O4hh1YhDfbA

(Edited to clarify these are not the best songs in the show, there are better songs and in a wide variety of genres!)
