Best Lines of the Episode

[DizzyIzzy]

The pilot when he hears the smoke monster/MIB...even before Hurley:  "ut oh"

[KoKoNut]

When Hugo and Kate found out about Jin and Kate and Hugo broke down saying, "Dude..."  Okay. That got me. I started bawling.

[Beej]

Sayid to Jack: Welcome back to hydra Island

Sayid: At least you didn't have to paddle

[Madam P]

Jack X to Locke X: "I think you're a candidate."

Bernard X to Jack X: "Good luck, Doc.  I hope you find what you're looking for."  (Isn't that the same thing that Bernard said to Jack the last time they saw each other in 1977?)

Jack to MIB: "They're not my people".  (I like this because I think it means that the other candidates aren't his people, but the leftover Others will be (eventually) "his people".)

Sawyer to Kate: "I saw your name on the wall in the cave but it was crossed off.  He doesn't need you, Kate." ("He" literally is referring to Widmore, but figuratively, it refers to Jacob.)

------

As has been said already, I loved the overloading meaning they keep throwing on tag lines:

"Whatever happened, happened."
"I wish you believed me."

There were SOOOOO many "echo'ed" lines in this episode -- ones we've heard before but now in a different context or from a different person.  More again of the "things-are-kind-of-the-same-in-alt-timeline-but-with-a-twist" deal...

[Madam P]

When Sawyer took the gun away from Kate & Allie kid:  Not anymore doughboy

LOVED that one!

Also loved Jack's "I'm with him" as the Smoke Monster arrives...

[CaseyMac]

Line from Locke, then repeated by Jack:
He wanted to get us all in the same place, at the same time--a nice, enclosed space where we had no hopes of getting out of.

[relient k]

Not anymore, doughboy.
