Adele is right, their timing is rather strange. But in all honesty, I don't feel their motivations for wanting him are as important as keeping him from them. To us, he's an advantage, small though it may be. We have something they want, and that is a rare commodity for captives.

The Dome is too obvious though, as are the tunnels. And its harder to defend someone in the tunnels. No, our best bet would be to sequester him somewhere a bit less obvious.
