But Elia didn't die giving birth to her and Rhaegar's third child, she was murdered by the Mountain. So when did she have a third child, especially since Aegon himself was still an infant? And then of course there is the inconvenient fact that Jon has the Stark looks. There is no way Elia is Jon's mother. He's either Ned's son by an unknown woman, or Lyanna's son by Rhaegar.

In the first season, Bran asks Ned if a man can be brave if he is afraid, and Ned answers that that is the only time a man can be brave. Azor Ahai cannot be reborn unless he first dies. "Kill the boy." "What is dead can never die."

In the books, Kevan isn't killed by Varys until some time after Cersei's return to the Red Keep. Could be several weeks, but certainly several days later, at the least. They'll probably drag out the wait for Cersei's trial next season, so Kevan will have some time to try to deal with the death of Myrcella before someone -- Littlefinger??-- decides to off him. Frankly, I figured Varys wasn't going to be killing Kevan once he went to Pentos and Volantis with Tyrion.

Snow drifts up against the outer wall?

IRRC, Ghost was penned up away from the courtyard because he was annoying Wun Wun. So he wasn't in close proximity to Jon when he was attacked. We don't know where he is in the show. Either way, either Jon can warg into him when he's not close by, or he can't. Melisandre coming back to Castle Black is a little too convenient, so my guess is she's involved in Jon's "rebirth."
