Loki was a little amazed to find anyone else out in the snowstorm, but, when he was close enough to see who it was, his senses told him something immediately: vampire. Someone who wouldn't be bothered by the cold in the least. He was actually meaning to meet the vampire protector of Barton and Romanoff for some time, if only to sate some curiosity (as to why they would feel the need for a vampire protector). Apparently, Loki wasn't the only one who had an eye on the spies, although his own attentions had waned as of late.
Eric's Nordic roots gave him away before he spoke. While there were plenty of people who were blond, blue eyed, and tall, he just looked...completely Scandinavian in a way Loki couldn't describe without just saying the word.
"Eric," Loki said with a slight bow of his head. Only polite, after all. Loki really meant no harm, at least at the moment. "Out for a walk?" He grinned slightly. "Such a lovely day out, isn't it?" He was more amused than anything at how people seemed to hide away when it got the least bit cold. He had thought that humans enjoyed a 'winter wonderland.'
