Mira, Maria, and the other disciples also dispersed after the Sect Master left. They now had plenty of homework to do, especially Mira, who had many different manuals to read and techniques to learn, all in just a month.
Fortunately, she had enhanced comprehension and could put herself in a semi-enlightened state, so she didn't think it would be impossible to learn everything.
Maria, on the other hand, was thinking about something else entirely. Scenes of Mira getting beaten helplessly kept resurfacing in her mind, and she didn't know how to stop it.
It's not like she was losing her respect toward Mira or anything, but she couldn't help but wonder if there was something she could've done that would've allowed Mira to stand her ground more against Nova.
Could she have been more supportive? Or maybe, she could've gathered information on how Mira could maximize her power.
