Winston providing a makeshift bandage
Geoff is the shlimazel (unfortunate soul) literally in the line of fire when Adam and Winston struggle outside the cockpit in "Rewind". Adam's gun goes off, hitting Geoff in the left shoulder. Winston instructs Brooke to apply pressure to a pad over the injury, to reduce the blood loss, and to keep Geoff from dropping into unconsciousness. Presumably, he is the man on the stretcher carried out by paramedics at Portland International Airport, creating the diversion whilst our heroes slip out the back.
