With a snort and a roll of his eyes, Marcus didn't respond to that, unable to think of anything appropriate to say, though he couldn't quite shake the desire to mess with the bandage again. Knowing it wasn't a good idea, and that the tattoo needed time to heal, was what kept him from doing so, because the last thing he would want was to somehow mess it up.
Marcus could feel his eyebrows furrowing together in confusion at the statement, and after a brief pause answered, "Of course she is. And I can't think of anything that would 'come between us', as you say." Hell, she'd stood by him through the war and his imprisonment, so it seemed unlikely that there would be anything that could break their bond.
There was still something off about Roger's smile, though Marcus couldn't pinpoint why that would be, and made a note to pay better attention to the younger man's mood for the rest of the afternoon. "That all sounds wonderful," he said, offering a smile of his own. He'd specifically not planned anything else for today so that he and Roger could take as much time as needed. Chuckling lightly at the comment about the tube, he shrugged and said, "I'm sure I could manage it better the second time around."
He followed Roger without question, letting him cast the charm even though he was more than capable of doing so himself - he was concentrating more on the warmth emanating from where Roger had his hand for the Side-Along. Looking out over the view, Marcus was quiet for a moment before glancing back over at Roger as he said, "It's amazing."
