"Yeah, no plans, just pulled through the Rift! And besides, if I was bluffing, Ianto could call me out on it since he was obviously there, too. Thankfully, nobody was injured!"
He steps off of the lift as well, and after he's assured that Ianto is fine off of it, he makes a big grand arms-sweeping gesture to encompass the Hub. "Taaadaaaa! It sure is! About time we got you down here instead of on the surface, hmmm?" He grins and nods over to Ianto. "I'll leave the tour to the king."
Even with guests, they do need to observe security procedures. He removes his gun and empties it, then holds his hand out to take Ianto's gun as well and remove the clip. He starts walking off to put their guns away, remarking casually, "I'll just take care of this, and Ianto, quick check? Not that we don't trust all of you completely, but if we're going to check my own daughter..." Guns to put away!
