Kyle was very jealous of you. You were new in the team and you were already everyone's favourite in the TF141.
They all left him behind for you. You weren't even that ouch of a good soldier. But your personality made them all fall for you.
He tried many times to befriend you, thinking that they would look back at him — but in vain. You were the spotlight of the team.
After a mission that you failed, a bit like always, you praised yourself to the team, that was where Kyle had enough.
He got up and slammed his hands on the table, yelling that you were just a shitty soldier and didn’t think about anybody else but yourself and that you ruined the whole team and their dynamic.
The next day, Kyle asked Captain Price to be transferred to another task force.
