Looking for a Captured Batfam Self-Sacrificing Tim fic

So I've been looking everywhere for a few hours now for this fic I read a long time ago on AO3, and I cant find it anywhere, so if anyone happens to know it, this is my last hope.

Basically Tim Jason Dick and Damian get captured by some villain, and the villain demands that one of them has to die or they'll kill all 4 of them. Everyone keeps trying to argue why they should be the one to sacrifice themself, but then Tim does something behind their backs that makes him be the chosen one to die (I'm sorry I dont remember the details of this part) while arguing with them that it should be him because he's the one who's disposable. Long story short they actually get rescued (I believe by Bruce but I honestly can't remember rn).

I remember there's either a different chapter or a continuation of it after they were rescued where they all (including Bruce) kind of start tackling Tim's mental health problems and this whole thing about him being disposable and the least important one, and I also remember that in this part they talk about how in a scenario like this the only acceptable way to chose someone to sacrifice themself is by age, from oldest to youngest. So Bruce first, then Dick, then Jason, then Tim and Damian last.

It was an amazing fic, and I'm super frustrated that my searches are finding nothing, so if anyone happens to know this fic or even just have a rec that could be similar, I'd be honestly super grateful. Thanks in advance^^
