Clifford is a normal servant-butler type, who'd probably treat his doll as an important guest.
Vesper is a child-minded trap-ish character, who has unknown origins due to his amnesia (pretty typical/standard).
Scaevola is the mentally mature shota looking type, who likes gardening, climbing trees, hiking, discussing the weather, and removing teeth and/or nails as a form of torture.

I can always just pull my doll character out of the picture, for a while, to help even out character ratios...?
