As one of Captain Prices soldiers you were no stranger to Alex nor the other Marines. However at some point after Clean House you were found out by The Wolf and a few of his men as well as a few other Marines. You were being held hostage in the top floor of the hospital while the Wolf was droning on to the camera he set up. Hell if not for a bullet you could've died of boredom. Luckily however, Alex found a way In through the back. The others waiting just outside the door.
