You know when Stratt gives three hours for Grace decide what he thought it was "go in the mission or not", but actually was "go by his own will or go screaming and kicking"?
I think she did this for herself. She was hoping he would volunteer, trying to give herself a chance for a clean conscience at least on this matter. She would never admit it, but she wished so hard he would make things easiest for her. That he would give her a chance to say a proper goodbye. Because, after all, she cares about him (at least on the film, I didn't read the book yet)
