Ianto had to school his features to keep from quirking an eyebrow or laughing at the other man's delivery of that line, instead leaning in a bit as well himself and remarking back to Sulu slyly, "Well, yes. I suppose that I do have some tricks up my sleeve. I suppose that that means that you'd like for us to try some of them out tonight, then, now wouldn't you?" Just to prove that he could deliver the line and not make a fool of himself while doing so, Ianto took a pointed sip of his wine and managed not to choke or spill or anything like that. Points for him, if he did say so himself, which he did.
