Thomas's laugh was a little more strained. "I see I have much to learn of Dornish politics. Still, if it's a match that can be made, it'll be a fine one. The power of the Riverlands and Dorne joined in marriage...and ever loyal to Casterly Rock, of course."
The loyalty was true enough. Thomas had no issues with the current crop of Lannisters and didn't anticipate any in the future. Tyrith seemed content with the Rock and naught else, but who knew what went on behind those cool green eyes? The lion sleeps in wait, apparently.
"Have you thoughts on William's regency extending to kingship?"
