Great points. Defeating the ice dragon will be tricky (possibly emotional, I’m guessing, for Danerys). I’m also wondering if there is some sort of armor plating the dragons could wear that would defeat (or at least deflect) those nasty spears that killed the one last night? At any rate, that is going to be one epic battle!!
I was wondering if the other 2 dragons would actually try to defeat their brother; or, would they hesitate or outright refuse to attack him?
