Unlike the last Great Prophecy from the PJO series, the Prophecy of Seven seems to be coming true over the course of the series. The seven half-bloods that answer the call come together by the beginning of The Mark of Athena. And technically foes did bear arms to the Doors of Death in order to close them and get them out of reach of Gaea.

Also it may already be too late for Bob. If Bob was actually destroyed during the fight, he would reform. Except the person he was fighting was Tartarus, who may prevent his reformation. Even Damasen is not safe. Despite the fact that he can't be killed unless a demigod and god work together, that doesn't mean he can't be trapped or cursed as a new form of imprisonment.
