Protective John (specific search and rec request)
I'm looking for a fic where Sherlock and John were captured and John has gone into this mega protective mode(I think he's locked in some ongoing PTSD flashback? He doesn't recognize Lestrade at all and tries to kill him at first)and when Mycroft and Lestrade finally find them, John is ready to kill Sherlock in order to protect him from who ever captured them.
Can I get all the protective!John fics you've got? I don't care what he's protecting Sherlock from (Donovan and Anderson, bad guys, Mycroft) or what he does to protect Sherlock (punches someone, shoots someone, ect.)
Sherlock/John or no pairings only please.
