Laswell, was in the TF141 and helping them on missions. Like talking in the radio and helping them get in. But she needed a brake and gave you the job. Not telling anyone about you.

Now Ghost, Soap, Price and Gaz were in the plane and ready to get the mission started as they heard your voice in the radio and realized it wasn't Laswell

Ghost : "Wiate, your not Laswell" Soap : "Yeah, I know Laswells voice. Your not her" They were confused as whose voice from there radio was.
