this is a great comment.

My god, this writer is truly painful to read. This will be the last one of these I try to slog through. Shame, as these used to be a nice addendum to the shows.

It doesn't matter, Robert wanted all the Targaryens dead. He was super pissed that Dany and Viserys got smuggled out of King's Landing before he could kill 'em.

Yeah, she was supposed to marry his brother Brandon before the Mad King killed him.

Well, I believe the point would've been that he was doing the ultimate sacrifice/favor for his sister. If the theory is true and it was known that Jon was a Targaryen bastard, he would've been immediately killed by Robert's regime. Obviously we know Ned was the most honor-bound of dudes, and he probably prioritized…

Lyanna and Rhaegar, when he absconded with her and set off Robert's Rebellion.
