Jack grinned at the two of them. "Nice to meet you two as well," Jack shook the offered hand. "You must be Jeeves, then," he said to the taller man. "I've already met Bertie, so by process of elimination... Besides, you look like the world's most perfect valet, so I must have it right. Ianto here said you were well-dressed and looked very professional," he said, motioning to the man standing next to him, who blushed.

"As for our height, well, what can I say?" Jack said with a patented Harkness grin. "Taller men are more attractive. Guess that means we all know how to pick them, right?" he said, with a wink to Bertie.
