For some reason when I saw "Dan", the bald headed guy who seems to be in charge of the Tower, I thought of General Hammond on Stargate SG1. Of course someone else's playing Dan since Ron S Davis died several years ago. Though I can picture Davis portraying this character if he was still alive.
That was Glenn Morshower who has been in tons of shows and movies. He gets a lot of military type roles, like the colonel in Xmen: First Class.
Anyways, pretty good episode, those coil guns are pretty powerful. I would could see Nevelle taking over the Monroe republic but I can't see them killing Monroe off just yet, especially when they just introduced the whole my son is out there story line.
