She was acutely aware at the moment of how much she could easily tear him down, simply because he trusted her, and was somehow still very... innocent. Of course, since she knew Optimus was a decent, no, delightful individual and a good Prime (as much as he could, since he didn't know everything and was - whether he knew it or not - being worked against) she didn't want to do that.

Luckily, she didn't have to do it either, since she knew now that he would listen and try to change things, but nothing could be done from here.
