When I leveled up first it was a jedi knight, I got to the kiliks and they beat me down. I hated the ant people.
Started leveling my operative and had to work with them, I was disgusted.
Saw Vector, was disgusted he was a joiner.
(was light side) Decided to help certain people and he jumped to my side. My only thought was YEAH VECTOR LETS KICK SOME ANT ---!
Used him ever since, not any other companion.
