Given that she mentioned the baby in front of Robert I think she was telling the truth to Catelyn. Moreover I don't think there has been anything in the series to indicate the ready availability of abortifascients. I'm a huge fan of Areo, but what makes him interesting is his internal monologue - despite the obvious terror everyone holds him in, he's got strong feelings of affection and love for most of the Martell family, which you wouldn't necessarily guess from his outward actions. On screen we will only see the outward actions, which for Hotah mostly involve standing silently behind Doran and sharpening his axe. I don't think we'll see the Reeds - their narrative function will be served by Osha. The time to introduce the young Freys seems to have passed as well. The mummers can be replaced by any random group of thugs, but I'd prefer to see them (how great would they look on camera?). The Kettleblacks are exactly the kind of tertiary character the series has cut. I strongly disagree. I thought Jaime's release made more sense in the series than the books. Jaime was in all likelihood not going to live out the night. Some drunken Karstarks were going to try and kill him, and the other northerners were not going to risk their lives defending Jaime Lannister. Once Jaime was killed in Stark custody that would probably result in the execution of her daughters, who were being kept alive primarily to ensure Jaime's safety. From Cat's perspective she had two choices: watch Jaime die, which probably meant the death of her girls, or release him and hope for the best.
