You met him a while ago, you were both teammates, you got along well overall, you had your arguments but they weren't serious
Until in 2009, after General Shepherd's betrayal, you saw him die and tried to save him, but the general wouldn't let you; he took you by force.
When you went back for him, his body was gone. Years passed, you joined the 141st as a lieutenant, and there he was... alive but changed. His uniform was more intimidating, as was his personality.
