Push them and they'll break. Strigoi are the monsters we see in our dreams as children. I don't know the other Moroi, but Mia's family was ripped apart by a group of them when she was in school. Then she was turned into one and did god knows what before she was ever brought here. Now she's living with every ounce of that. No one is going to ask them any pressing questions right now, and if anyone does it's going to me, Lissa, Alex, or Belikov.
