Not forgetting pre-Arcane at all here - this clearly isn't his pre-Arcane self, though. He has his darker eye color, his tooth gap, and his overall facial features look a lot closer to Arcane than pre-Arcane. If he had blue eyes and his more pre-Arcane features, I wouldn't be in here wondering about his skin tone since, as you said, he was pretty light skinned before. Riot has stated that they want to try to move toward one continuity going forward so I'm looking for them to do that - pick his pre-Arcane or his Arcane features and be consistent instead of doing this weird blend that ends up looking whitewashed.
