Collision

Ana Lucia killed Shannon. She knows it. Sayid wants to kill her. She holds him back. Tied up. The two groups of survivors face each other. The tension is unbearable.

In flashback, Ana Lucia is a cop in Los Angeles. A man shoots her during a call. She survives. She was pregnant. Not anymore. She finds the shooter months later. In a parking lot. She kills him. In cold blood.

On the island, Eko takes charge. He carries wounded Sawyer to camp. Jack treats him. Ana Lucia frees Sayid. She stays alone in the jungle. Guilt is her only companion.
