I think the interesting thing though is that we are thinking of a specific Skrill and a specific Night Fury. From as far as we know the Skrill might not the sharpest of dragon because of how long he has been frozen for.

Plus Toothless might be a genius even by Night Fury standards which may even them out if they were to fight each with each other out if there is no outside help. The insteresting question is what happens when two average members of their respective species clash.

Since the two dragon are both strike class which means they are more closely related to each other then other dragons which means you would expect them to have the same intellectual faculties!
