Jenn had been making drinks as instructed when she heard Mir yell for Emry's. She had been wondering when their Master would discover the broken string and it would appear that he finally had.
Her heart pounded in her chest, she would have her answer any minute regarding whether Mir could punish them. Could keep her safe from herself. She didn't feel bad about doing this to Emry's and framing him like this, she was helping him. She genuinely thought that he needed to be punished for his screw ups, it was the only safe way to alleviate the guilt that must plague him every waking moment. That was how she would feel after all, it was natural.
She took a deep breathe and carried the drinks through to the music room as she had been instructed, she needed to know that her Master would do more than scold the boy. Spank him or may be whip him a little.
