I think Jack has an idea about how dangerous Kate can be. Unless he has lost his mind, he can't forget about how desperate the marshal seemed to find out where she was.
He pshawed the idea that someone as willowy as she could be any danger to the marshal after being warned about her by same. It wasn't until Hurley pointed out the gun that he entertained the possibility she might be able to kill the weak-as-a-kitten antagonist whose survival might mean an indefinite jail term for her.
Maybe that's it. Maybe I just think that Jack is lame because he's an inconsistently written character. Or an idiot. Or both.
That could be the root of my disdain.
Maybe (P-C/virgin scenario) that's why he was dragging Boone around, and when he couldn't get an answer other than "my sister...mumble mumble" Locke decided to tie him up and get away.
It bothers me that no one seems to be freaking even a little about the fact that there is at least one mysterious crazy person on the island who was not on the plane, has kidnapped a helpless woman and tried to kill a man for reasons unknown, and he's still out there. Even if everyone's assuming Claire and the baby are dead, Ethan is still a danger, and no one even seems worried about it, much less taking any precautions.
I'm suspicious of Locke. I don't think he's actually intending to hurt anyone, but he could end up helping them to death. Boone is an idiot for not demanding to know why and how Locke did what he did to him. But then, we know Boone pretty much is an idiot, so there.
I was both sorry and not-sorry that Shannon was not really dead. Because I don't like her and wouldn't miss her, but this episode she just started getting interesting. I don't feel cheated by the fake-out; I found the purposeful hallucination even creepier than her death would have been.
I guess I'm still counting feeding 40 odd survivors for at least two weeks as save-ish.
I count Locke's first boar and the water find as about the same level of save; in both cases, food and water were in the jungle for anyone to find, but it took Locke and Jack to get off their asses and actually find it.
Jin would have to be catching a whole lot of fish to match a couple hundred pounds of boar.
We saw him pull in three good size fish with one throw; if that's the sort of success he's having, and he's fishing every day, he's probably bringing in the same level of protein as Locke bringing in 100 pounds of boar meat on a more irregular basis.
It'd be nice if they salvaged up some snorkeling equipment -- we had at least two divers on board and one has their dive bag -- and went hunting for crustaceans.
While I'd certainly be glad of boar meat if I were there, fruit seems to be abundant enough that no one would be in danger of starving by this point (even if the consequences might be somewhat unpleasant). I actually think Locke might represent more survival value in keeping people from getting lost and killing themselves in the wild than by directly providing meat. As long as he's out hunting, they don't have to and risk stumbling down a ravine or getting bitten by something dangerous (spider, polar bear, Lostzilla...).

Finding either is easy. Collecting? Boar wins in the complexity department. No one complained of not enough water once the water was found.

I don't know how long it would take them to die of malnutrition, but they'd be well on their way with such an imbalanced diet. I count nutrition as more important than medicine, myself.
...Uhhh, yeah. If he ever goes out hunting again, as opposed to telling everyone he's going out hunting but oh! those wily boars! when in actuality he's staring at hatches and giving surly young prettyboys lessons in Renaissance art history. Which, not so much with the protein-getting.
I'm not sure that Jack's skillset is all that useful, though. A surgeon can't do much if he doesn't have scalpels and clamps and anaesthetic and instruments, so barring some really spectacular coconut-technology, he's pretty much down to country doctor level. And country doctor stuff, well, at this point Sun does as good a job at that as he does.
Pfft. Every doctor is going to have trauma medicine experience, and a surgeon much moreso. There's no way an herbalist is going to have as much medical value as a surgeon. I'm not saying she's not valuable - but applying basil to a severed artery is not going to be as effective as somebody who can sew it up.
Ditto what other folks said - there's fruit aplenty, and pigs and fish. People would've figured out how to hunt. You can't figure out how to diagnose a systolic murmur.

Perfect opportunity for someone to step up and prove him replaceable. So far, only Jin has a shot.
