Regan and Kent have a pretty close relationship- she’s always trying to build him up and congratulate him on his accomplishments. I’m kinda thinking they are so close because ever since they were younger, they never quite “fit in” with the rest of the family. According to simblender Regan is bi and Kent is gay.
When he’s not outright antagonizing Kent, Cornwall works on increasing his logic skill. His LTW is to become the law and unfortunately, chess sets are not as ubiquitous here as they are in Widespot.
