Or not accept it and don't take what the catalyst says as the only option.
Everything, like the nature of the Crucible itself, is born out of circular logic. It was worked on and created by organics as a way to destroy the reapers, but no one knows why and how. The solution only works if you get there and activate it, and by getting there you are told you have rendered the other solution (i.e. the reapers) useless. But that is not true, the reapers are still going to win no matter what because you still need the catalyst to do what you set out to do and he is not helping, so the options he gives you are not really a solution to a problem but an alternative to... I don't know, but one even contradicts his purpose. I don't know because the crucible is not really the solution to your problem, thus it shouldn't be a threat to the catalyst's plans who already has a solution that is working perfectly fine: the reapers. So if the crucible is not a solution and it turns out that the catalyst, who claims to have some connection to the reapers (possibly created them) is offering me another solution that doesn't really address the problem, I don't have to accept it.
