Oliver stared at Leela in the sort of wonder that comes of trying to picture something that sounds too amazing to envision. "Oh wow." The words didn't really convey his current feelings, but they were all he could think of to say. Hopefully something more eloquent would come to mind when he saw the actual sight, although he already had the impression that it wasn't likely.

He followed quickly after Leela, glad he was used to running after the Doctor. He was impressed by how fast she could be even when she couldn't see. "You go there a lot, huh?" he asked, only realising belatedly that he should be careful not to imply he didn't think she could handle something as well as other people.
