So, the scene of Jamie is clearly not the same one as Beth’s, but considering how much she hates him, I’m still willing to put money on the fact that she’s talking about him.
We cannot see who she is talking to, but Jamie is the next person shown after that trailer moment.
She makes her comment at the 1:24 mark, and the sun is shining, whereas Jamie is shown in a dark room with a roaring fire.
