It just seems extremely ODD Alduin would attack for no reason whatsoever. Seems like a missed opportunity for a good plot twist by Bethesda. Like maybe you're really Alduin's other dragon brother....or the dragonsoul inside you is actually his son's or his father's or some other random thing.
Or did I miss it entirely? Does the game actually ever tell you why Alduin attacked Helgren? As far as I can tell, he has very concrete objectives (ie resurrect all the dragons)...attacking Helgren seems pointless.
