[He started to argue because since his second wife found out about her and bolted, he's kept her under wraps, but River continued and he stayed quiet.

The information he received kept him quiet as he mulled it over. She could read minds--thoughts? Someone like that would never suffer betrayals. They wouldn't need to be sly or creative to ensure someone was being truthful with them. They wouldn't need to flush a room full of freshly rescued scientists out an airlock to find one traitor.]

Yeah you do. Power like that's gotta be frustrating. Sounds like it's something you couldn't turn off if you wanted to.

So, yeah. I got a daughter, since you already know. I don't like bringing her up. Not a lot of people I can trust right now. She, uh... Yeah. Very powerful. Power she can't control, so I built her a machine to help her control it. She's safe there. Happy. She can't accidentally hurt anyone and no one can hurt her. But she's got access to everything. Anything with a camera or computer is hers so she doesn't feel left out.

[In other words, yeah, he might be a little sympathetic towards River. That's not something he can be accused of anywhere else. He might also be very intrigued by this power even if it makes him edgy.]
