Anyone else feels like that this sentence from grayfia's reveal in the rating game, even though i'm pretty sure that rias and her team, along with rias's family, ajuka, and rudiger, were the only ones to figure it out due to how the announcer reacted(<>) "The person who immediately responded to this was — Rias-neesan. She stood straight up and widened her eyes, but she was speechless. And then her expression turned serious — and it seemed to show pain." means that rias is feeling scared that grayfia may be trying to steal issei from her like how she felt in the short story "Let's go to Onsen"?
