My absolute favorite was when the fort-bomb Izzy made made their glass shield explode and the Grips were covered in paint (Espically how Chris looked after it). XD It was awesome. And the skull Dunken made was pretty cool too, I actually applauded when I saw it.
I also liked how Justin was finally losing his girl-control...then upset when he got it back.
And, since I'm already talking too much, I LOVED Explosivo.
I hope Izzy will be back again with another alter-ego.
