Forum:Where was Joker going?

SPOILERS AHEAD! [are we still doing that? :P ]

When you make your decision at the end of the game, and the Citadel discharges that wave of energy across the Galaxy through the Mass relays, where was Joker going in the Normandy when he gets hit by it mid-Mass Relay jump? I was under the impression he had remained in the orbital battle during the final assault in London [/SpartanRacer]
