1: He is childhood friends with his older brother's wife, they had connected with their shared questions about God, church, and the future. After he moves away for college all they have are phone calls, even though people know he's gay they can't help but question his close relationship with this woman, especially since shes married to his older brother. (hucklerobby, angst, guilt, complicated relationships, and mental health problems (including postpartum depression) )
2: Dennis was turned in the late 1800s and has lived a long life. He kind of wants to die, and his coworkers/friends/love interests are concerned with his lack of self preservation. He is experienced in terms of relationships (was married to a fellow vampire for a view decades) and careers (being a doctor is just something that is on his checklist until his first day in the Pitt, were he realizes that this is actually something he wants to do instead of drifting along) (minor hucklerobbot, past relationships and moving on, questions on what makes someone human, and mental health problems)
