Yes, another thread about the Mass Effect 3 ending. I apologize for the redundancy. I haven't seen this specific question asked very much, so I figured I would make a thread about it.
So at the end of the game when you're on board the Citadel with Anderson, the Illusive Man appears out of nowhere. Regardless of how this is possible or what he's even doing in this situation, I have a question: since he clearly has the drop on Anderson and Shepard, why the heck doesn't he just kill them both while they aren't looking, then make his own damn choice? It should be clear to him, and the Reapers too considering he is indoctrinated, that Shepard has up to now been resistant to his plan. So again, why not kill them both and then use the Crucible to control the Reapers? Why can't he just do this himself? Why go the risky route of trying to talk Shepard into doing his bidding once again when he's already pointed out that Shepard is now an obsolete tool, no longer needed by Cerberus?
Am I missing something here?
