The doctor turned at Jack's quip with an 'Oi!' before turning back to his patient.
"He does have a point, Doctor. You do leave the break on," Martha said, clearly not comfortable being the patient, being used to TREATING the patients.
"Perhaps, but he doesn't need to let them in on that little secret." Of course he seemed more amused than angry, but that was the Doctor... He gave a disapproving look as Jack leaned in to kiss her, a look that was clearly ignored by both parties. Getting in the way of the scan like that... the scan that finished as he started leading the group off. And what a group it was... that General was a mystery that needed to be figured out. But not right now.
"Come along, Martha Jones." he said it looking at the scanner. "I'm afraid it's the infirmary for us." And with that he helped her up and led her down the other corridor. They'd have to catch up with the tour later.
