I'll never join you!

From Create Your Own Story

YOU: I'm not working for Cerberus! You guys killed more people than the main villain in the last game!

THE ILLUSIVE MAN: Saren was a pretty crappy villain, though. And our work was all for the greater good of humanity.

YOU: You fed my entire unit to THRESHER MAWS back on Akuze! What the hell did that do for humanity?

THE ILLUSIVE MAN coughs and mutters something about TESTS and EXPERIMENTS.

THE ILLUSIVE MAN: Gotta say, Shepard, I was expecting a little more gratitude for the whole "Spent billions of credits to bring you back from the dead" thing.

You say:

• Thanks for that, but I'm not joining you.
• Why DID you do that?
• I noticed some changes.

OR:

• What's changed in the two years I've been out?
