JOHN!

[Aims his gun at Jack] Step back, Jack.

Jack:
What did you do?

Locke:
What I had to. Now step back.

[The phone rings, Jack and Locke look at it]

Locke:
Stay away from the phone.

[Jack runs and grabs the phone as Locke tries to shoot it]

Jack:
What are you doing, John?

Locke:
I don't wanna shoot you.

Ben:
Do it, John! Shoot him! Do what you need to do-

[Ben is silenced as Rousseau knocks him out]

Locke:
Please. Put the phone down.

Jack:
No. You're done keeping me on this island.

Locke:
[Thumbs back the hammer] I will kill you if I have to.

Jack:
Then do it.

Kate:
Jack!

[Locke hesitates then lowers the gun]

Locke:
[Sadly] Jack, you're not supposed to do this.

[Locke leaves as Jack answers the phone]
