First Aid nods slightly, conceding Jean's point -- but not entirely.

"And how old are you, Jean? Thirty years old? Forty? Megatron, Starscream, Shockwave...all of them have had millions of years to reconsider and end the war. Starscream himself used to be an explorer and scientist, but he chose to be a warrior instead, and now he's so bloodthirsty that not even his own side can trust him. And it's not as though we never tried to make peace with them -- Optimus Prime tried many, many times, both on Cybertron and on Earth, and each time Megatron broke his word and attacked us again. It would be lovely to think that Mortanne could give them a reason to change, but...given their history, I think it's far more likely they would simply lie to her for the chance at enslaving this island and taking its resources for themselves. And I pray that never happens, but if it does...I wanted you to be forewarned, Jean. Since you chose to take up this burden."
