if dany did show up, completely curbstomp the lannisters and took the throne, and then proceeded to stomp stannis whole army as well, would stannis be like "hm right of conquest i guess. you're my queen now"?/
he built his entire rebellion on the notion that robert had a right to the throne before, via right of conquest rather than viserys, or would he just say "piss off, my claim's better"?
