"Oh," Logan's voice softened as he realized that she'd been trying to say something nice and he'd jumped all over her. While 'I just know things' wasn't nearly enough of an explanation and he was still suspicious of how she knew, he realized that he'd overreacted a bit.
It was just that you didn't go bringing up something like that with a perfect stranger. Not in that way. He hurried to step in front of her, his face calmer now.
"Sorry, it's just... a touchy subject. I-it was... interesting to meet you, River. I'll try not to snap on you if I run into you again," he said with a small smile, attempting to be polite.
He nodded his head and stepped out of the way so she could pass him.
