That explains why “Task” has a seventh episode, even though — and spoilers start here for those still catching up — the fifth included the long awaited confrontation between Ruffalo’s Tom and Pelphrey’s Robbie, and the sixth left Robbie dead. Sure, there were a few loose ends that needed knotting, including the exposure of the mole within Tom’s task force, the apportioning of Robbie’s stash, the killing of most members of an outlaw biker gang and Tom’s forgiveness of one foster son and surrendering of the other. But the tension in the finale is largely moral. This story is really one about forgiveness, which can take time.
