Like she needed to be brave around him? Please. It was more of the fact that she knew there was a newspaper dispenser nearby and she needed to get past him to get to it. Because clearly he wasn't going to take her word on the matter as he was from her future where she betrayed him. Sought her birthright from what she understood. But more than that, she knew that someone had to fight for magic, and he wouldn't do it so she had to.
Still, he was insisting she was the only one who would want him out of Camelot beyond Merlin for trivial reasons and well, that was something else entirely and she would let him find out about the wrong version of Merlin for himself.
"Impossible..." Placing a coin into the dispenser, Morgana turned and handed it to Arthur, "But true."
Noticing the lack of complete hatred in Arthur's voice at the term magic, Morgana quirked a brow. There was an inherent distrust and obvious derision, so she would still be on guard. But it was still something. But she didn't bother with the comment about no one having the kind of magic to do this as he was pushing for more information.
"I already told you where we are, Arthur. And if there were a way back, do you honestly think I'd still be here? I've been in this place for months now. The way home is the way you came here. Through a magical... Seal... The new religion speaks of a war between good and evil and for whatever reason, it saw fit to bring us here."
Glaring to the side, Morgana shook her head. She didn't have the patience for this. She needed to go see Loki. She needed to get the words out of her mind so they could warn the others.
