There's a warm grin for Harry as the lift lowers him down into the Hub; Jack's made his way over to the base, to wait for him there, and he's got his hands in his pockets, bouncing back on his heels as he waits. Of all his magical visitors, Harry's definitely one of his favorites- definitely, considering what a pain some of the Ministry officials can be- and definitely the one he gets the most to boot. Which- there's certainly a reason for that, and one that Jack doesn't mind in the least. So the smile, a warm welcome, and an easy greeting off,

"Harry, Harry. How went the trip? Not too much trouble, I hope."
