Sarah shrugged at the indication of the weather, but she was willing to remain out there to protect certain things in the medic facility. To her, that was worth every numb finger and toe that she suffered. Besides, it wasn't so bad as long as she kept moving around. Her body was fine to produce heat and face off against the snow and wind.

"I've been in worse conditions," she replied simply, though she did follow him curiously. She reached out to take the little pack that he offered her, finding the gesture oddly sweet of him. It was, quite honestly, the first thing he had ever given her. "Yes, I know how they work, thank you," she murmured softly. She turned the little packs over in her hands but didn't use them just yet, savouring the idea that Yuri gave her something.

"I suppose I should let you get back to your work now that you've set me up to stay warm," she murmured absently, still studying the little packs.
