Lost Finale (SPOILERS - Do not enter if you haven't seen it)

[Croyles]

I am so annoyed at the end of this season, i thought this would be THE END and everything would get explained! I didnt know anything about a 3rd season. What the hell is going on?
I wanted everything to end on the second season.
It really frustrates me on how little they are telling us.

The only theory i can be bothered to write: Pen's father is running the Dharma initiative.

Alvar Hanso is running the Dharma Initiative. Mr. Widmore does run a laboratory, though, the same one that manufactured the pregnancy test that Sun uses in Episode 216 "The Whole Truth." However, I haven't seen a connection between Hansocorp and Widmore Labs.

Yeah but hasnt like nearly no one seen Hanso? There would be more than one person running it anyway.
Im more inclined to say that the flashbacks are real, but I guess there is the possibility that everyone is infected and thats why they are seeing things. But.....nah...
