The Queen was also stunned when the siren went off. She looked at Nora immediately and asked, "What's going on?"
Nora didn't bother with her. She merely glanced at Barbarian, hesitated a little, and then ran upstairs.
Barbarian followed behind the Queen with a hint of baffled surprise in his red eyes.
He hadn't stolen anything, so why did the siren go off upstairs?
He wanted to go and take a look, but he then thought of how dangerous the Schmidts' castle was at the moment. He had to protect the Queen. As soon as the thought formed, he stopped in his tracks.
However, the Queen said, "Let's go up and have a look too!"
Surely Black Cat hadn't mistakenly trespassed into someplace, right?
She had to save her!
She mustn't let Black Cat fall into Nora's clutches.
Only then did Barbarian follow them upstairs.
