[Halo 2]How did the Gravemind acquire the Prophet of Regret when his body was vaporized by the Covenant cruiser?

Chief gets grabbed by Gravemind while sinking to the bottom of the lake long after the temple was destroyed. In the Gravemind cutscene, how does he have control of Regret?

In Halo 2, Master Chief is teleported directly into the middle of his next mission after his chat with Gravemind. Same goes for the Arbiter. 

I assume that Gravemind could teleport Regret's body back into his grasp.
