Did K plan all along for J to go back in time?
When Boris gets away after they go to Wu's, K tells J imprisoning Boris instead of killing him was the worst mistake he ever made. But when J suggests they go get him K tells him to forget it, and then K makes no effort to get to Jeffrey Price first to stop Boris from going back in time to kill him, almost as though he is resigned to it. Even in the scene right before he disappears he grabs his space gun and sits In the chair like he knows what is going to happen.
So did K actually want Boris to go back in time to kill him so that J would go back as well and help him correct his mistake? If not, why didn't K make any effort to stop Boris In the future?
It does seem far fetched that K would take that kind of risk and have that much foresight to see that outcome, especially when not just his own life but the safety of the world was at stake. But I can't figure out why he would make no effort to stop Boris from going back in time in the first place.
