Desmond's visions of Claire and Aaron.

[David3]

Every vision Desmond had last season was of a event he would be present to witness in the future. How could he have a vision of Claire and Aaron getting on a helicopter, if he's not even on the island? Does that mean he'll soon be back on the island? Was he lying in hopes of getting himself off the island (plausible, he was going to get Charlie killed before to get who he thought was Penny to island)? I'm going to assume he returns.

Desmond left the island? Did I miss something?

Answer: Yes

Well, he has been wrong before. He saw Penny instead of Naomi when they took the helmet off the parashooter.

Flashes of Charlie drowning and Charlie slipping on the rock weren't visions where he would've been present.

I don't think he ever saw Penny, he just guessed it was Penny from seeing the photograph, and thought that saving Charlie somehow magically changed Penny into Naomi.

Desmond was lying. He actually saw himself getting on the helicopter, but to give charlie motivation he told him it was Claire. That's my theory and I'm sticking to it.

[Claude]

Shouldn't he have only seen Claire/Aaron getting on the heli if Charlie was in peril someplace close by? Meaning: All of his visions related to saving Charlie, why is this Claire one different? Maybe he is just lying. But if he is, that's not cool.

Desmond's not a saint, Claude (despite his priestly history). He would do almost anything to be with Penny, just like what Michael did to get Walt back.
Character's have to have conflict whether internal or external to stay interesting, look at Claire for a example. Now Desmond is pretty much set for life in the conflict-area since he and Penny have this "will they find each other, or won't they find each other" situation, but that doesn't mean his character can't get more layered, shady, or interesting.
