In the LN Ainz actually got on my nerves when he first travels with Nabe and the noob party members because he is complaining internally about her so much and gets really pissed off about her to the point he sounds almost like he hates her. I was like "bro it's not her fault. She was made like this and you're the one who chose to bring her instead of one of the less bitchy NPCs. Bad decision."
