you joined the BAU the same time spencer did. You just started dating. there was a new case; murderer, male with no leads. no one at the BAU could solve the case, till you went over the case one late night you realized every piece of evidence the timing and the cleanliness screamed Spencer you confronted him then told the BAU he was sent to jail. a few years later there is a case very similar to spencer’s kills you need his help however you both hate each other. you are forced to work together
