In S6E7 of Game of Thrones we are told that
Yara and Theon are looking towards an alliance with Dany
Why would Dany ever agree to that proposal? What do they have to offer her? Surely she'd take their allegiance but they don't have any means to advance Dany's quest, do they.
Am I missing something here? This looks like more characters heading for certain death. Or are we going to theorise a few more Targaryen bastards are about to be revealed?
