Animate animator from animation clip

Hi there!

So, I'm trying to make a cutscene in my stupid simple game. I have multiple rigged characters and I'm trying to control/puppeteer them using an animation clip. However, it doesn't seem possible to control my character's animator from an animation clip. I don't see any other feasible way to construct a cutscene.

I hope this screenshot will illustrate what I'm trying to accomplish. I want to control each characters' animation, especially facial animations, during the cutscene. But this doesn't seem possible? How else can this be done?
