EXTINCTION

Earth rumbles and shudders.

"You will go through the gate to the Alpha Site and assume command."

"Sir, you're more qualified..."

"It's not negotiable, Jack! This comes directly from the President."

"General..."

"Enough!" Hammond's tone leaves no room for argument.

Fires are drawing nearer.

"Yes, sir," Jack concedes. "SG1..?"

"They go with you."

"Yes, sir." Jack comes to attention, solemn eyes holding those of his Commanding Officer. "It's been an honor serving with you, Sir."

Hammond smiles. "Backatcha, Jack."

Life on Earth is ending.

"We will survive, sir," Jack promises.

"I know that, son."

There is no coming back.
