the last episode of arcane season 1 had various tropes like the villain monologuing to himself and someone overhearing an important detail. It was a bit of a weak conclusion.
My issue with them doing Bilgewater is it's kinda pirate themed and you know what other live action is pirate themed? One Piece. I don't want LoL's first live action to get any negative flack over that when people who don't know either IP start trying to make connections. Hence I hope it's Shadow isles instead of Bilgewater.
