specific Morgan as hostage fic

I'm looking for a specific fic where while the team is working a case Morgan goes to pick up lunch or coffee, encounters the unsub, and is taken hostage. The unsub has issues with dominant women, so Morgan calls JJ and pretends she's his hardass boss, setting her up to do the negotiating. Morgan also tells the unsub to figure out what his demands are, because you don't take hostages if you don't want something. In the end, the unsub demands to talk to his brother. The team realizes the brother is also the unsub's son and the root of the case is incest. Any ideas on where I can find it?

I'll also happily read any other fic where Morgan is a hostage.
