Impulse is actually an agent of the Reach. The pill only cures Neutron of his exploding thingy, not of his mind control, which just goes dormant. Impule's powers come from his metagene, activated by the Reach. Then, he gets sent back in time, to tell Blue about the end of the world, motivating him to let Green play with his scarab. The League would have been suspicious if they found him experimented on by the Reach (assuming that they found a way to reset the scarab without green), especially right after they fought Black Beetle. They might have suspected that Blue was being controlled by the Reach.
