When you force a group of people to live together, that Pack will naturally split into groups and there will always be the strong leaders, the weak and the floaters. The mean girls, as Vanessa puts it, fall into the strong side, the weak are Nadias group and the floater is Perez. The weak will always applaud anyone who hurts or annoys their nemesis's and this is why Nadias weak group like Perez.

Nadias group are not strong enough to stand up to the strong group, so they are egging Perez on which makes him feel wanted and special, so if you want to blame any group for the discord, blame Nadias group not the 'A' team.
