I think he was more apologizing for snapping at her. He also didn't know that she tried to throw herself into the accelerator either. However, she wasn't forthcoming about Tom watching the leap either.
This required more of a terse conversation on the sidewalk, but I don't know how you do that with the constant leaps. Again, Magic is in charge, and he needs to make executive decisions that are going to keep Ben focused and moving forward, leap by leap.
I did like the point Tom made that maybe the actual technology of leaping is always going to be a one way trip.
