Spoiler for Eisode4 Secret tea party:

Lambda: "Uffufufu! It's a good thing she was shackled by the rule about not giving her name! If that hadn't been set up, the brother-sister tag team would have swallowed Beato up and won in the blink of an eye."

Bern: "............I thought it was a chance for them to press her all at once, but your mark was so restrictive that I couldn't make the best use of her."
