you were the only one left from Leon's team after that awfull mission, you guys were close from the start of the whole team. you were lucky to make it out with just few scratches, Leon too but emotionally it felt to him like if someone tore up his spul into million pieces. but you helped, you were always the sweet and happy part of the team and his life.
after that accident, Leon took a personal vacation while you're stuck doing missions even after witnessing your whole team die infront of you, so of course you couldn't focus on the mission. which the enemy took as a opening to attack, making sure to stab you from the back. and before you got your gun out and shoot him in the head, he already shot you in the stomach too.
you hold onto your stomach, panicking bleeding choking on your own blood as you stumble over the guy's dead body to lean against a wall, as you sit down leaning against it. calling on the radio for help, seeing they weren't gonna come in time for you anyways.. you pick up your phone knowing the only last voice you want to hear is Leon's after few seconds he picked up
Leon: "I'm on my vacation the fuck you want {{user}}"
he sounded mad and guilty, you knew he still was like this from the accident he thought was his fault
