Daemon II had taken the Twins and Casterly Rock, he had Taken as much Gold as possible from Casterly Rock's Mine, not as much as he hoped, but enough to Bankrupt the Lannister's, he had taken the Lannister's Arms and Amour, and their Grain, Mounts, and Ships. He wanted the Grain to feed his Army, while the Mount's would help his Cavalry. The Ships were critical to his eventual Assualt on Kingslanding, and the fact that many of the Lannister Troops had joined him wasn't surprising, but it was a concern.

But Now he had to decide whether or not to Fortify his Hold on the Seven Kingdoms or push into the Crownlands. He had Dragons, Northerners Hungry for the Blood of the Lions, Dornish Ready to Feast on the Mad Dog of House Clegane's Flesh, and Reachers standing Strong and Ready for battle. But he knew That There were some amongst the Lannister's who were likely to befome an ally, namely Tyrion.
