"I am 'the great Captain Jack Harkness', after all," he adds, quoting Ianto's words. He raises an eyebrow back at Ianto, as if to say 'if that's what you want, challenge accepted'. It should be noted that he is very much aroused, regardless as to whatever games they may or may not be playing with a stopwatch.
