NCIS A Perfect 300? Plus, Who Is Planning a Major Life Change? http://tvline.com/2016/03/15/ncis-season-13-episode-18-recap-300th/
Eventually, in part due to Gibbs’ nudging — at the bequest of Dr. Confalone, who aimed to “kill two birds with one stone” by having the troubled Marines talk to each other — but also because of the daughter he’d kept at arm’s length, Davis lets down his defenses and recalls enough intel to help point Gibbs’ team in the right direction, finding a camera that recorded the ambush and this identifying the sniper. It was then a massive waiting game, outside a Virginia air strip, wondering whom the sniper would try to shoot out of the sky and when. Dealing with his own ghosts (as well as insomnia), Gibbs embedded himself deep in the brush and spied/gunned down the shooter just moments before he might cause an international incident by killing a Saudi oil baron.In the aftermath of the successful op, Davis joined up with the MusiCorps rehab program at Walter Reed, delivering a soulful rendition of “Hallelujah” over the closing montage, where we learn that McGee is ready to put a ring on it with Delilah, and even more significantly, Gibbs is able to retire his busted couch-for-a-bed and finally return to the bedroom he long ago shared with Abby Shannon.
