"Hey Shepard, a ship full of researchers has gone missing, and they have a sweet-ass vehicle with them you could maybe use." "Go to hell, I don't care, I left Cerberus so I'm not listening to you!"

"Hey Shepard, some AI thing is about to take over the world." "Go to hell, I don't care, I left Cerberus so I'm not listening to you!"

"Hey Shepard, here's where the Shadow Broker is, didn't your friend want to find him?" "Go to hell, I don't care, I left Cerberus so I'm not listening to you!"

So you see, the post-game DLC makes perfect sense for a Paragon Shepard who told the Illusive Man to shove it.

RPGs let you make choices, fortunately this one doesn't let you make completely and utterly stupid ones. A Paragon Shepard may hate and reject Cerberus, but they're not stupid enough to refuse intel and resources when the stakes are so high.
