hold my heart more gently than you do my throat
Master Anakin Skywalker has been captured; his padawan races to a small outpost deep within Separatist space to rescue him.
Because he needs rescuing. Because he's his master. Because, even if Anakin doesn't know it and even if Anakin is happily mated to some other omega, he's his alpha.
Because maybe if Obi-Wan risks life and limb to save his master before the Separatists can neutralize the threat that the Hero With No Fear poses to their cause, his master will realize that Obi-Wan is no longer some youngling in need of coddling and protecting.
At the very least, maybe he'll stop bringing up that unfortunate business on Melida/Daan.
