it.
Then let's get moving.
I could take Vincent,
and he can sniff something that belonged to Charlie,
and I can help.
I said no, man.
Hey, Locke,
hey, look, you know, a lot us don't just wanna sit here waiting for news.
Thanks, but we're set. Anyone else is just gonna slow us down.
Okay.
Maybe I'll just put together another party.
Good idea.
We're going North. I suggest you go South.
Come on.
Never thought I'd see the day, Jack.
You barge into my O.R. You work on my patient.
You didn't have to do this procedure.
I don't have to do anything.
Yeah, of course you don't.
I chose to do this procedure -
this emergency procedure -
because when this girl crashed in the E.R., they called me.
I was right upstairs.
You should have stayed upstairs. And how did you find out?
One of the nurses came to get me.
Who?
Oh, thank god I have you and some anonymous nurse to rescue me.
She told me that your hands were shaking.
My hands were not -
- You cut her hepatic artery.
She was in a car crash, Jack. Her insides were a mess.
- You made a mistake.
- They called me.
I don't care whether or not they called you,
- you made a mistake.
- Are you lecturing me?
If you were upstairs, and I was in a restaurant having lunch,
then why did they call me?
How many drinks did you have at lunch, dad?
Jack!
Jack!
It's a good thing you were going in a circle.
Not much of a search grid, but
we never would have found ya otherwise.
Did you find anything?
No.
You should go back to the caves - Sayid's leg.
I dressed sayid's leg.
You found me. We can find Charlie and Claire.
Now, do we have a trail to follow or not?
- Jack, this was my fault.
- What?
I hunted with Ethan, I spent time with him. I never sensed anything...
off.
But for everything that I know about hunting and tracking,
whoever he is, he knows more.
If we catch up with him,
I don't want anything to happen to the only trained physician on the island.
So go back, be the doctor. Let me be the hunter.
Can we go now?
Follow me.
I'm trying to help, and all the guy can tell me is go South?
Like what? I'm gonna get in his way or something?
We're all tweaked, man.
Locke's just feeling it like the rest of us.
So what?
I got five guys who are going out there with me,
putting our necks on the line to try to find Charlie and Claire.
All I'm saying is
I'm getting sick of being treated like a second-class citizen around here
because Mount Baldy can bag a boar.
He knows a lot more than how to catch a boar.
Mr. Locke's a warrior -
he can hunt,
he can track stuff, and he's the only one who brought knives.
So if it were me, I'd listen to him.
Well, I don't want you to.
You understand?
You stay with Hurley.
I might not be a warrior, but I am going South.
Back home,
I'm known as something of a warrior myself.
We mark our progress by line of sight.
Tie these off so we don't get lost.
You can lead us back to camp, right?
If nothing happens to me.
Maybe I'd better take marker detail.
Anything?
Not yet.
- If you can't find the trail -
- I'll pick it up again.
We need to rest for a minute, to get our clarity back.
You're gonna take a break?
It's gotta be almost 4:00. When the sun sets, there's no way -
It's 4:25. And, yes, I'm taking a break.
Can I talk to you for a sec?
Would it kill you to give the guy a little space?
It might.
Stop that.
What?
That.
What's going on?
I didn't believe her - Claire.
- I gave her a sedative.
- Jack, you can't -
she told me someone was after her, that she was being attacked, and I -
she just seemed so out of it.
I thought that her pregnancy was amping up her stress, and I...
I didn't believe her.
Jack!
What is it?
Look familiar?
It's Charlie's.
You think it just came off?
No.
He's leaving us a trail.
They went this way.
I'm not so sure.
There's another trail here.
- What do you mean, "another"?
- These are footprints.
People moved off this way.
Charlie's leaving these for us to
