Ability of Prediction

Present, looking at Eva's pissed expression and Livia's revered look as she looked at Eva, Ace knew something was amiss, and he might have missed something interesting.

So, he didn't speak directly and used his thought transmission with Eva, "Why are you looking so aggravated? Is she that difficult to handle?" 

Eva was startled momentarily when she heard Ace's voice, but her expression went stern as she replied without opening her mouth, "This bitch is crazy!" 

Ace felt amused when he heard Eva's exasperated voice and curiously asked, "What happened?" 

Eva then didn't hide anything and told him about Livia's thief-fanatic persona and how she wanted to become the Sky Stealer follower. She was even willing to become her maid or mere servant.
