Eini's question surprised everyone, Pavel included. There wasn't anything on the plan saying that he would battle a fake Shiba. His master said that Pavel would be facing Shiba, so he didn't think that Shiba was fake while they battled.
However, he noticed that the Shiba he had been battling and the one who killed the Ice Goddess differed in power, but he thought that since their battle was a performance, Shiba wasn't giving his all when battling. Thus, he felt that Shiba was really good at hiding his power, but he never considered the possibility that someone changed places with Shiba.
"What are you saying, I have been hiding my power, that is all. I am sorry for keeping it secret, but sometimes hiding something from allies helps to trick enemies."
Shiba tried to ignore what Eini said as if she was just upset for Shiba hiding something from her, but Eini wasn't planning to let the matter go with just that explanation.
