How do you think Adarfo handles foreign affairs?

We all know what he would do in a revolutionary ending, just join the CSP and thats it.

But how does he handle it in a desperate reform ending? Romus is still King, the nobility is basically powerless and he is PM in a unicameral state.

How does he interact with Intermerkopum or Grace? He can't exactly join the CSP as long as a Monarch still reigns.

I have never interacted with him so I genuinely know next to nothing about him as a character.

Also, different topic, but can you still reform the nation with him if Manus is at war? Or does he not interact with you because you're a monarch?
