Claire's sonogram has the date October 22, 2004?!

Back at the hospital with Claire, she is looking at her sonogram which in a potentially huge revelation, has the date October 22, 2004 instead of the original Ocean 815 date of September 22, 2004. What exactly does this mean for our alternate timeline?

[UPDATE: Damon and Carlton have confirmed that the new date was a prop error, so we can stop reading into the different date.]

After that little bombshell, Claire is approached by a Detective Rasmussen and another officer looking for Joan Hart which is one of Kate's aliases. Claire covers for her as she hides in a supply room. Kate emerges after the police leave.

Claire gives Kate her credit card to help her out and then admits that she doesn't know where she came up with the name Aaron. She says "It's like, I don't know. I knew it or something." So we have another instance of our Losties, and not just the ones at the Swan site in 1977 and those we've seen touched by Jacob, seeming to remember bits of the original Oceanic 815 timeline. Also, Kate tells Claire she should keep the baby. It seems that little pieces of the original timeline are still falling into place.

Dogen spins a baseball + Jack takes poison pill

Back in Dogen's office, he is spinning a baseball and concentrating on it. It seems likely that he is using it to think about thinks, much like Sawyer says he reads books to do the same in season 5. On the table, there are some written pages and the top one is slightly visible, but at a bad angle. If anyone can translate the Japanese, leave a comment.

Jack comes in and says that Dogen speaks good English for someone who needs and translator. Dogen tells him that he doesn't need one and he does it to remain separate from the people he's in charge of because it makes it easier when they don't like the decisions he makes for them.

Dogen tells Jack that he was brought to the island like everyone else. When Jack questions what that means, Dogen says that Jack knows exactly what he means. This seems to spook Jack.

Jack once again questions what is in the pill and Dogen says that he can't explain. Dogen says that Jack needs to trust him and Jack says that he doesn't trust himself. Jack then tries to swallow the pill and Dogen quickly springs into action, hitting Jack in the chest and performing the heimlich maneuver until the pills comes out. Dogen then admits that it's poison.

So why exactly do they want to poison Sayid? What exactly did their previous "test" tell them?

Sawyer throws his engagement ring for Juliet in the ocean

Kate finds Sawyer sitting on the dock. He tells her that it's his fault that Juliet is dead, not Kate's, because he convinced her to stay on the island in 1974 because he didn't want to be alone. He delivers the devastating line "I think some of use are meant to be alone."

He the reveals that he was going to ask Juliet to marry him and we see him holding the ring which he pulled out of the box (see that here). He then throws the ring in the ocean, tells Kate that she can make it back to the temple by night and leaves her there, where she breaks down.

Just a little editorial note: Josh Holloway delivers a stunning performance in this scene that rivals his excellent work in season 5.

Ethan is Claire's doctor at the hospital, Kate seems to recognize the name Aaron

Back the "alternate" timeline, Kate rushes Claire to the hospital where she is quickly taken inside. Kate is clearly paranoid about the police presence in the vicinity.

Once inside, Kate gets impatient waiting for a doctor and goes to find one herself. The first one she comes across is none other than Ethan Rom, who is going by Ethan Goodspeed here (since he is Horace Goodspeed's son). Once he gets inside with Claire, the scene is reminiscent of their scenes in the season 2 episode "Maternity Leave."

Ethan says that she can have the baby now or he can give her some drugs to slow the process down. He drops the line "I don't want to stick you with needles if I don't have to," which if you recall he did regularly at the medical station. Once she chooses to wait, an alarm sounds and in her panicked state, she says "Is Aaron okay?!" When Kate hears the name Aaron, her eyes widen and she looks stunned as if something in her mind briefly clicked with the original timeline (check out photo 8).

Everything then calms down and Claire can see Aaron on the screen once he's moved back into position. Kate is holding Claire's hand and that moment together is reminiscent of the moment they shared when Aaron was born on the island, but just slightly. The scene seems to solidify the bond these two have, no matter what events occur.

Kate finds Sawyer at the barracks, he unearths a box

We see Kate wander into the barracks looking for Sawyer. The barracks looks are run down and dilapidated, just as we see them when Sun, Ben, Frank and Locke were there in season 5.

Kate makes her way to Sawyer and Juliet's old house where she observes him pulling up some floorboards and pulling a shoebox out from under them. He pulls out a small pouch from the box, which we later learn contains and engagement ring intended for Juliet. When he hears Kate, he pulls a gun on her before noticing who it is. He walks past her out of the house, hardly saying anything to her.
