"Merlin?" The disbelief clear in her tone, which said nothing about the irritation that flashed through her at his words. However, Morgana caught herself quickly enough, stilling her angered thoughts immediately as common sense came in. Typically it would have come much sooner; however, as controlled as Morgana could be emotions did know how to get the best of her. There had to be some mistake. As open to the people as Morgana attempted to be, she couldn't honestly -far from it - claim to know the face of every servant in the castle, let alone every subject in Camelot. However, he should have recognized her and his reaction of seeing her practing magic should have been one of shock, possibly even horror, than a simple statement of observation. Which meant that ... There was a mistake or, he was from a world from the ... other versions of Merlin. This entire thing was promising to give her a headache.

"You know a Merlin." Statement, not question. "That's -- " Bizarre as hell. "interesting. He's here, you know. However, he's very likely not the one you know." From what she'd seen, all the other "versions" of Merlin were old. Her world was the only one that had both Arthur and Merlin has contemperies.

At least in your world it sounds as if, once you have the key returning home should be simple enough." Unless the key was difficult to find. Nothing ever turned out as easy as one expected, with these kinds of things. Morgana is wanted to ask about doors through darkness and the ships (she'd seen a movie with flying boats and then there were space ships), when she realized that she hadn't introduced herself. Usually she was much better with that.
Holding out her hand. It was an interesting change to do that in order to have it shaken and not the back of it kissed, "Forgive my manners. I'm Morgana." She said by way of introduction.
