More evidence of winter in season 3

I really do think winter will be done within season 3. And not just for a quick flash forward or anything. There’s mounting evidence. From what they’re wearing, Lottie wouldn’t wear layers like that in summer. To the fact that the episode titles for the last 3 episodes of the season are so finale/rescue coded. I could be totally wrong, but I have a feeling they’re getting rescued this season.
