Looking for a crossover fic, possibly with The Sentinel?

Hi everyone!

This is going to be vague and I'm sorry, but I can't remember much about the story. I'm pretty sure it was a Sentinel crossover, or at least used the Sentinel and Guide idea. Hotch and Reid were a Sentinel and Guide, maybe, and were the main focus of the fic? At some point in the story Jack and Henry were kidnapped or injured, I think, and the trauma caused them to awaken. I think Jack was a Sentinel and Henry was a Guide. Is this jogging anyone's memory?

Thanks for the help!
