LOST IN THE SAUCE
The Sauce Apostle
I was thinking that sending the youngest one to the place closest to King's Landing was pretty risky, but I'm guessing she didn't think shyt would be so quick to jump off. Otto straight up said that he's putting them all to the sword, she should know him by now.She sent him there cause it was closer.
She was trying not to send him too far away. She didn't know that the Greens had the same game plan or she never would have sent him.
