If he's stuck try leaving the area, waiting a sec, then re-entering.
If your on PC you could try to resurrect him through console as well.
He's not even attempting to move. He's just in the hallway. He says 'I'll talk to you once I'm settled in the control room'. It's as if I I need to prompt him to go there somehow.
I'd suggest reloading a save before that and trying again.
Not an option. I've done a whole lot since then.
