Yelena's not at imminent risk of freezing solid, but she's definitely shivering despite the heavy parka she's bundled up in. The fresh bruise splashed across one cheek is probably a sign of how exactly she's been staying, if not warm, at least on the right side of human popsicle.

Despite having been aboard the Barge for nearly a year, her first thought when she spies the golden retriever amidst the snow drifts on the deck isn't 'shapeshifter'. It's something more akin to puppy, and her gaze flicks up, searching for any accompanying human before she approaches slowly, unearthing one hand from her pocket to offer her fingers to sniff.

"Hello, gorgeous," she says, low and calm, and warmer than most people wandering around on two legs are likely to ever get from her.

That might be slightly embarrassing in a moment, when she gets close enough to read that sign.
