[THEORY] Will Sion like Noxus for granting him immortality?
So I was rereading Sion's lore because I main him when I had a kind of miniature epiphany. Sion, for those who don't know, killed Jarvan I centuries ago, and was resurrected in present day Noxus. However, Sion is but a mindless creature with no memory of his former self. The only way that Sion can remember his former self is by being in the heat of battle, smashing the skulls of his enemies.
But what if Sion doesn't want immortality? What if Sion will see himself as a monster and hate Noxus for what they did to him? Through his quotes and his lore we know that Sion has a distaste for Swain and modern Noxus. So its not out of the question that Sion could reject Noxus once he regains himself through bloodshed.
And maybe this is just wishful thinking for something huge to happen in my main's lore, but what if Sion took out his rage on Noxus in the most baleful and ironic way possible?
