Okay, I haven't loved the story line because it has been so obviously coming but Dany and Jon Snow is starting to grow on me. The look on her face when he said he'd lead the group going beyond the wall... She might just be the best actor on this show, she conveys so much without a single word.
I think Cersei is full of it and that the pregnancy is a ploy to cement what she sees as Jamie's wavering loyalty after he stood up to her on how to kill Olenna, met with Tyrion in secret, etc. She's stringing him along, promising everything he's ever wanted, and with her if something sounds too good to be true it almost certainly is.
