It always seems like Cayden and Jack are always squaring off about who's better. Cayden clearly has a bodily advantage (weight/height) but jack..well, he's a cute little Pegasus. Needless to say he has wings and a smaller build, unlike Cayden. Each time the discussion seems to end with Jack showing off his wings and Cayden, instead of countering just blushes and tries to act nonchalant.
