Damien had nearly missed the reaction Merlin had to the modern devices suddenly going on at once. He was used to it, he always had the top of the line, most advanced stuff to own. Afterward, he looked at Merlin and realized that it would probably be a shock due to the other man being from such ancient times. Damien thought maybe it was a good idea not to show off that grandly too often.
But he did smile as he saw the sorcerer spoke of being impressed. He felt a need to make certain he was fine with all this, as it was probably a lot to take in. "Thanks. You're very impressive too. But.. umm, I hope all this didn't alarm you too much. I bet it seems like a lot since they probably don't have this stuff wherever you're from. But.. well.. you could probably find better clothes too." His hand briefly touched the sleeve on Merlin's upper arm. "These are okay, I guess, if you're comfortable in it. But I have an expansive variety of other clothes that you might like to try. I don't mind loaning out a few, I have way more than I should." He laughed at that part.
