OH NO YOU GOOGLED IT….. no it’s just something I (Viala) jokingly came up with while we were discussing that scene/writing it!

It’s been a while since I’ve thought about it, but I’m pretty sure the idiom was meant to be along the lines of a combination of two-faced or a snake in the grass, like… giving more thought to it I assume I was thinking like ‘keeping the two-headed bear at a distance’ bc if you let it come too close, you can only watch one head, and not be able to see what the other is doing. I’ll probably give it more thought and make it snappier and add it in to some future chapter ^^; sorry you tried to Google!!!
