This is my second favourite episode and with good reason. Since "All The Best Cowboys Have Daddy Issues" nothing really happened with the hatch, until now.
This episode also has the best falshback of any character. This episode is about Locke trying to do what the Island asks of him, while Boone follows along. The flashback is about Locke finding his parents and bonding with his father until Locke realizes his father needs a kindney, after Locke give's his father the kindney, his father leaves him and locks him out of his life.
A very exciting episode, especially when Boone is in the beach craft and the plane falls. The music that goes along with the ending both in the flashback and on the island. One of the most eventful and suspensful episode of the whole series. Definitly worth watching.
Locke- I've done everything you wanted me to do, So Why Did You Do This! WHY
