Your lunatic brother!

Eva felt a knot form in her stomach as Karl remained silent, his gaze intense and unwavering. She had never seen him like this before, and it made her uneasy.

"What's wrong, Karl?" she asked, trying to break the tension between them. She reached out to place her hand on his, hoping to offer some comfort.

But Karl didn't respond to her touch. He just continued to stare at her, his expression unreadable.

Eva's mind raced as she tried to think of what could be causing this sudden change in Karl's demeanor. Had something happened while she was away? Was he upset with her for some reason?

Finally, after what felt like an eternity, Karl spoke.

"What do you think you're doing?" he spat out, his voice laced with frustration.

Eva was taken aback by his sudden outburst. She had never seen him like this before. "What do you mean?" she asked, hoping to diffuse the situation.
