The Orchid. Anyone else find it funny that the fact that Sawyer held on to the well's rope during the flash to a time before the well or the Orchid was built, means that the reason some unknown (?) group will eventually notice that area and build a well is because a rope is embedded within the earth, lol. And with the well built, then perhaps Dharma discovers the energy and subsequently builds the Orchid station as we saw in the premiere.

Ben @ Faraday's mother revelation. Anyone else notice the musical sound effect during Ben's reaction to Desmond revealing that Eloise was Faraday's mother. As if it was a surprise and...as if it made sense to him (Ben) knowing what he must already know.

Ji Yeon. Sun was pregnant with Ji Yeon on the island and gave birth to her afterwards off-island. Ben warned Jack that once they all go back that they will never come back. Shoudn't Sun get that same warning to say goodbye to Ji Yeon? Does Ji Yeon need to come back also?

Jacob vs. "Christian Shephard". Anyone else think that it will be an important revelation to Ben that Jacob didn't tell Locke to move the island, "Christian" did. In fact, "Christian" told Locke when he entered the cabin, that Jacob's not here, but I can speak for him. When Locke left the cabin, he told Hurley and Ben that he needed to move the island. Only Ben moved it, not Locke. And in last week's ep, "Christian" reiterates that he told Locke to move it not Ben, and that listening to Ben never did him any good. But if moving the island was never Jacob's instruction, was that the right thing to do? Also anyone notice that, with the exception of Jack, the "Christian Shephard" entity has never appeared to anyone else who could have identified him (Sawyer, Ana Lucia), only to those who don't know him (Michael, Locke)?

The Smoke Monster. I really would have liked to delve into this mystery even more. Remember when Ben summoned the smoke monster to kill Martin Keamy and the rest of Widmore's mercenaries, he emerged from a secret entrance in the barracks covered in soot. Did he travel all the way to the temple underground somehow? The same place in the temple where the men in Danielle's crew went and were supposedly "infected" by the smoke monster? And Robert, Alex's dad, said that the monster was a security system for the temple - I want more answers, lol.

Desmond and Daniel. They've met three different times now 1) at Faraday's lab in Oxford in 1996, 2) while Desmond was in the hatch waiting for his replacement, and 3) on the island when Widmore's freighter showed up. The chronological order is 1-2-3. The actual occurring order is 3-1-2. Just found that interesting.
