Like the thing where Locke mentioned having a bomb in his backpack... and then moments later he's passing a backpack to Jack... why on earth did he take his off i have no idea but anyway. But it was painfully obvious he had done the old switch-a-roo with them.
Then to add to that he explains that the plane was an obvious trap because of the lack of security and electric fence thing. And again moments later they're at the sub with no security guarding and no fence. Yet no one has a brain cell to rub together to notice this!? So the plane is a trap but the sub isn't? the sub had no security at all on guard and they only appeared after nearly everyone had got inside! what kind of shit security is that?
If the plane scene had been 2 or 3 episodes ago then I could have bought everyone's stupidity or forgetfulness. But seriously, they walked from one place to another and suddenly forget everything Locke had just told them?
And what was the deal with Sun? She's a walking talking clumsy screw up who must struggle doing even simple things like eating and drinking without accidentally choking. I'm surprised Jin hadn't strangled the silly sod to death by now. The other week on the flashback 2 guys are fighting with guns and she stands right in the frigging line of fire instead of stepping out of the room as told. She was fucking told to run and yet she didn't do anything.
Now here the bomb goes off and somehow she's piled behind a frigging ton of debris!? What the fuck was she doing before the explosion? Pulling it all on top of her herself on the off chance it went off? How can anyone get their legs trapped in such a way? I mean.. she would have had to jump backwards, lift her legs up, then slide them down behind the pipes... and then stifen her backbone up so she wouldn't topple forwards until that huge unit fell forwards onto her chest.
Seriously how on earth did she manage to get that much shit on top of her and get her legs behind the pipes? HOW?
Morons the lot of them.
