You just have to convince her that "it's not alpha" to be dumb and she will be smart, its that simple.Cleo is just innocently dumb, I don't think she's capable of malicious thought. That being said, innocently dumb can still cause situations that hurt people quite easily, which is why they're generally an archetype that I don't pursue at all.
Imagine her nerding out because its alpha, you can use this gag every update and i will never get tired of it tbh.
