LOST-5/2 Something Nice Back Home

I wrote a synapses for this episode, but it got erased and I am too lazy to write another one. Basically Jack had his appendix taken out by Juliet and Bernard. Charlotte knows Korean, and Faraday likes her. The mercenaries survived the smoke monster and are leaving the island. Claire wakes up in the middle of the night and finds Christian holding Aaron. In the future, Jack and Kate are living together and are engaged. Jack sees Christian at the Hospital. Hurley continues to get visits from Charlie.

Some things I noticed:

• The smoke detector went off when Christian came. Could he be the smoke monster

• Does Jack have and appendix scar in the future?
• Does Jack know Aaron is his nephew? He told Kate that Aaron wasn't even related to her.
