Why should I?

Miranda had already been waiting for Nial to return to her to discuss the offer.

Since the day after the dungeon breakout, he seemed to have disappeared, only to reappear all of a sudden.

Not even his mana traces could be sensed for the period in between.

Because of that, Miranda hoped that Nial had learned to control this weird type of energy he released by now.

When she sensed his presence from further away she realized that her assumptions were proven to be correct. Nial was actively releasing dark energy, even if it was not much.

And the moment she was able to see him, Miranda could tell that the young man had changed quite a bit.

His demeanor had changed radically and he seemed to be much more confident than before, and it looked like he had grown more ambitious.

Of course, there were things the Old Medic didn't know, but she was oddly confident in the young man.
