Lost fic
I'm pretty sure it's on Ao3
I only really remember the beginning
It starts with Obi-wan and Qui-gon returning from Bandomeer.
It's night time at the temple and Qui-gon takes them directly to Mace's rooms, leaving Obi-wan on the couch, wakes Mace up and basically saying he can't train Obi-wan
Xanatos might have died on Bandomeer.
Mace will check on Obi-wan and notice he's not well and taking him to the healers finds infected whip marks I believe.
Mace might become his master.
Thanks for any help.
Edit:
Never mind, found it. Here it is if anyone's interested.
