Oh, and even though Chavez says that he and Sandra planned the escape, Gibbs quickly ascertains that Scott orchestrated the whole thing by introducing Chavez to Sandra two years ago so he could get the prison break ball rolling and just tag along. “He’s been playing you,” Gibbs says.Furthermore, Scott didn’t escape to get back into the spy game. No, he’s out for revenge. See, his Russian buyer in 2001 was also his wife (she was the blond in the aforementioned photo), and he wants that list of agents because they’re the ones who executed the raid that led to her death. It’s a hit list, and Morrow’s on it.The team races to his house, but it’s too late; Morrow’s dead from a bullet fired through his study window.And then, you guys, this show has the temerity to tell us it’s to be continued — with no new episode next week! So. Apartment mystery solved. Case not solved. And it’s the best kind of case, with a surprise whodunit and a deeply personal motive for a much larger crime that’s revealed in the final minutes.
