Nicki was the only one that got dismissed from the Alpha's chamber tonight while Nadia and Greta stayed behind. They weren't allowed to leave like her probably because of everything she told the Alpha which caused the fight.
At one point, she began to feel sorry for them when she found out from the Alpha that he gave them a strict warning to stay away from her after that last time in the diner hall, yet they failed to obey it.
Now, they were certainly going to pay for it. She had no idea what kind of punishment Nadia and Greta were going to receive, however, Nicki had a feeling it was to be a great one since the Alpha made an account of how many people got hurt because of what they caused and how they could have died too.
The last thing she witnessed clearly in the Alpha's chamber as she was leaving was Nadia falling to her feet and begging for forgiveness. So, Nadia knew how to beg for forgiveness? When she doesn't even show mercy to other people.
