Review of Ho'opa'i (Revenge)

I'm binge watching Hawaii 5-0 on Netflix, up to episode 1-21. Enjoyed every episode so far EXCEPT this one - it was sooooo very lame. The kid in the episode is around 12-14 years old, looks 12-14 years old, yet plays the part and is treated by the other actors like he's 5 or 6. Completely unbelievable.
