Leonel managed to protect his backside, albeit just barely. Giving Aina access to Earth Force though… Very bad idea.
Aina ended up giving him a list of things she would need to make the first batch of pills and they actually weren't so bad. It would be a simple matter to trade for those things through the Dream Pavilion. Even with all those ridiculous restrictions they placed to suppress the Vast Dream Pavilion, there was still a great deal of advantage you could get from them if you knew how to make use of those chances.
Leonel knew, though, that out of respect for Aina, they would definitely have to go and see her father.
She probably thought that he would forget, which was why she was still clinging to him and was being a bit defiant about letting him go.
