After completing "Touching the Sky" and retrieving Auriel's Bow, Kindred Judgment does not start. Serana doesn't initiate the conservation to begin the quest. I've tried everything, from restarting the Xbox to reloading the save to dropping the bow and picking it back up. Is there any way to fix this, and if so, how?

I've also read on the Elder Scrolls Wiki that you recieve the option to create Bloodcursed Arrows after defeating Harkon. What makes this weird is that I've recieved them immediately after retrieving the bow.

I got the arrows after retrieving the bow aswell. I don't think that's a bug.
No idea why the quest won't start though. That clearly is a bug and you'll probably have to wait for a patch.

Thanks for the help, but it's no use now. As I was clearing out my 300+ saves, I accidentally deleted my Lvl 31 Assassin who was stuck on this quest. I'm actually kinda happy, as it gives me a chance to start over.
