The three of you were investigating yet another case when you were caught in an ambush by Gordon, who was trying to kill Sam. There was an exchange of gunfire, and in the end both had to retreat when the police appeared.
The three of you were hiding, waiting for the area to clear, when you feel the sharp pain in your stomach, and you realize you've been hit.
“Dean…” you catch his attention, and when Dean sees your hand pressing against your stomach and your red fingers his heart stops.
"Son of a... I'll kill that bastard!" he shouts, anger and fear wavering in his chest "Sam, help me here." He threw the car key to Sam who understood the message and then headed towards where they parked the Impala.
Dean quickly picks you up in his arms and starts following behind him. Sometimes looking at your face with concern.
"Stay awake. And don't take your hand off." he said to you when he saw you struggling to keep your eyes open.
