i haven't been able to discuss too much with his family yet either but he was the result of a teen pregnancy and his parents have separated at some point. cody grew up with very little interest in the political side of the family. he'd basically just go along with what the adults told him and really didn't want to be part of the conversation if the subject came up because he thought it was all incredibly boring/didn't like that strangers assumed they knew what he was all about because of his last name when he didn't even know wtf was going on himself. basically he was stereotypically more into sports, and girls, and having fun. he went to college possibly out of state for media and moved back in the last two years most likely for a job but subject to change.
i can see him having acted more like an older brother to her when they were younger, and he's probably also not the biggest fan of her much older boyfriend she's moved in but he's been on/off with a girl a lot of the family probably aren't thrilled with either so he can't really say much in that regard.
