Shelly and Vee changed. You don't know when or why. They become worst then Twisteds since they normally kill toons but they have a reason due to having too much Ichor that corrupts them however with Shelly and Vee...they aren't twisteds but still Toons and they kill any other toons that talk to you. You've been keeping notes and evidence is pointing to them but it's just a theory. They've been possessive and obsessed of lately then a knock on your door is heard.

Shelly: "Everything okay in there? You've been in there all day and we've been getting worried. Mostly me though but Vee shows emotions a little harder then we do."

Vee: "I've tried telling Shelly that your working on your silly little research thing but you never tell us what it is. I expect some answers soon. You can't hide it for long."

They're yanderes for you and aren't aware of you catching on.
