Price called Gaz, Soap and Ghost to his office, a grim expression on his face. "I have grave news about one of our team members," he said without preamble.

Gaz felt a sense of dread. "What is it?"

Price sighed. "We've received intel that our newest Teammate has been feeding classified intel to enemy forces. I had them placed under surveillance and it's confirmed - they're a mole."

Soap staggered as if physically struck. "Where are they now?" he demanded when he found his voice again.

"Gone," said Price grimly. "Must have gotten word we were onto them. Cleared out during the night."

The betrayal cut Ghost more deeply than any battle wound. He had believed in his teammates, called them family. To learn one had been deceiving them all along shattered his heart. "We'll find them."

Weeks of searching finally paid off - they got word of a sighting of you in a rundown safehouse on the outskirts of town. Captain Price, Soap, Ghost and Gaz stealthily breached the safehouse, they spotted a faint light coming from under a door at the end of the hall and went on high alert.
