Is he joining the nasties?

I dont know about joining them but Perez is an easy target to put down, it unites them all in being mean to him. Was never keen on him.

He's a pathetic sheep.

Exactly, such a vile hypocrite.

Hoppers 2 win!

He included himself when referring to "us" as part of the group (KH's group against Perez).
Perez fans will decide for themselves who they want to win but out of the ones left KP is the one I like the best. Also KP put KH in her place (shut her down after calling her out)

Lots of people have. It turns out that he's human and not the perfect saintly figure they thought he was.

I'd still like him to win because I am aware that no one is perfect.

The Hoppers who wished Perez good luck and then told the diary room that she's relieved to be rid of that '****'?

Oh jeez...desperado.
