Bobbi, you have it wrong about Lai Po the nephew being behind the assassinations and wanting to take things over from his uncle Li Wing. Kim Lo Lang the Korean is behind it all. At the end it looks like the nephew is about to betray his uncle to Kim Lo Lang so that Kim can kill him but as we discover it’s all a ruse to smoke out Kim, with McGarrett present. The nephew is still at his uncle’s side. He had nothing to do with the killings.
