People seem to forget all the things you've already gone through with the Scions. I'm not surprised that they aren't surprised. Hell, it wasn't that long ago that we were all swooped up and sent to an alternate dimension of the same planet, but different still. Traveling in space, and going back in time seems negligible compared to that, or about equal in outrageousness.

I did wish that there was a bit more time aboard the ship though.
