>>113024693I would put the villain be part of the mistery the whole time, in the mistery police series for example, the guilty character is part of the mistery, she or he might not be the most obvious one but it is part of the thing it is investigated.
In Zootopia they form a partnership, the friendship gets broken, they got back together and follow some leads and end finding it is the sheep, but you could replace the sheep with any other side character and it would have been the same, she is not a good villain.
