Sun runs away from Locke & hits head, loses ability to speak English

At her garden, Sun cuts her hand and is then startled by Locke. He tells her that he found Jin like he promised and has him back at his camp. She mentions that he killed everyone at the temple, which he once again defends by saying he gave them a choice to leave and they were confused. Suddenly, Sun makes a break for it and Locke chases her through the jungle until she hits her head on a tree branch and is knocked out.

Later, Ben finds Sun unconscious under the tree and asks her what happened. Sun can only speak Korean, but does manage to tell him that Locke did this to her.

It's very interesting to see Sun choose not to trust Locke over being reunited with Jin, considering that's is her only real goal. Her distrust of Locke is so deep, that she refuses his offer. This seems to possibly indicate another white rock for Jacob's scale since she chose to give into Locke's temptation.

Sun is angry about waiting around, goes to her garden

At the beach camp, Ilana is passing the time by cleaning her gun as Ben tries to convince her that Richard does not have the answer to their problems. Ilana says that Hurley will bring him back and they should wait. Sun gets frustrated by the conversation and storms off after jamming a knife into the table.

Sun goes to her garden which we haven't seen since the season 3 episode "D.O.C." Jack follows her out there and mentions that it seems like she first planted the garden a hundred years ago. Jack then proceeds to tell her about the lighthouse and mentions the Richard and the candidates and Sun doesn't care about any of it. Jack tells her that they're on the island for a reason, but again, Sun isn't having any of it.

It's interesting to continue to see Jack as the man of faith, trying to convince Sun that they are destined for something bigger than themselves. It certainly seems like he's taken the full leap at this point, but that was apparent during the dynamite scene of "Dr. Linus."
