chord was hired to be kurt's boyfriend. he should have had that role but darren brought in a lot of money with "teenage dream" so they changed it around and pushed sam into the background in favor of cash. and then basically they were like "lol let's promote darren to a regular and not chord" and it was basically a mess, they were so rude and inconsiderate towards chord, and then they were like "well he can come back if he wants" after fans went insane at RIB over it. and of course he said no because who would want to go back to a job he was initially pretty much released from? tl;dr: i dislike klaine, blaine so, so much and darren by default.
