that will still work! barrett has been in boston since he was out of high school. he went to boston university too! majored in chemistry, then went to medical school and graduated this year with his MD, so there's a lot of time between there that they could have randomly met. even though he's a doctor, some might wonder why he never entered law enforcement instead because he has a quick response to criminology and forensics through barry's knowledge. can they be best buds? cause i feel like these two could get into some ridiculous shit together. barrett could have been persuaded into joining him in that never-happening-again bikram yoga class or attending some other classes that they keep trying to do only so that they can cross it off some list. barrett will also slip his pending application as 'god father' because he just wants a child to spoil without having to steal one
