pluto is named cole delaney.
"Cole was the last person to take up residence at Solar Heights. Because of this, he was always slightly ostracised from the others. Eventually, he was asked to move out of his room in order to extend the kitchen and he got moved to the dark, cold basement. Cole is moody and spends a lot of his time alone, listening to music - even Eaton spends less time alone than he does. He’s now just waiting for the day when they actually kick him out of the house. He knows it must be coming sometime."
