It was clear he was missing something here. Luke couldn't think of any reason they'd ally with the Sith--no enemy could possibly be greater than that divide--but he also wasn't sure he wanted to learn too much of his own future.

Luke gave Ben a look out of the corner of his eye. He hadn't believed Ben before, and it had cost them both too much. Doubting his son's insight wasn't something Luke wanted to do again.
