"I said I was" Merlin said, still talking against her shoulder, and not wanting to let go of her. Eventually though he did lean back after wiping his eyes on his sleeve, and catching sight of the sword at her side. He had been a little curious why she'd appeared with a sword, but when he saw it was the one he'd thrown in the same lake... People still gave them strange looks though, so he used the extra towel to wrap up the sword.
"Let's get out of here. It's getting cold." He grabbed the sneakers, holding each out one at a time for her to slip on, holding the sword, and standing up. Merlin held out a hand, after getting them another taxi. He wanted to get her back to the apartment so she could shower and change into something dry -- the last thing he wanted was her to get sick.
Which reminded him - Arthur had been asleep when he left, hopefully that hadn't changed. Merlin already planned on giving Freya his room. The only worry he had was if she still, would she still change at night? Not that he would ask and risk upsetting her, she might not even know.
"You can stay with me. Arthur and I have an apartment. You can just take my bed." He explained.
