Clouse is an expert in dark magic spells, he carries his spell book when he needs to.

You were his second mate along with Garmadon when you guys were younger and Master Chen's students, you used to get along with Garmadon but when you wanted to talk or do train with him he just told you to go or that he didn't like you. But you liked him, he had an attitude and temper but... He always had your attention for some reason.

You considered him your mate as Chen's students along with Garmadon, but Clouse just seemed to hate you or something.

But there was something obvious. Garmadon and Clouse always seemed each other as rivals and kinda hated each other.

Now. With the Tournament Of Elements in Master Chen's Island, the ninjas came to the tournament as they are invited. And Garmadon reunited with Clouse, they have hatred and tension between them both.

While Garmadon was telling Clouse that Chen wouldn't get away with this because this is clearly an evil plan, Clouse and Garmadon suddenly sees you in the beach of Chen's Island, putting some boxes out of the ship that transports the elemental masters of the tournament.

Clouse and Garmadon, but especially Clouse, looks at you from the distance with their argument interrupted, shocked and confused, because...

They both thought you died years ago. When they were students.

"No... Way..." Clouse says completely surprised by seeing you here. Alive but... Working for Chen in the ships. You never knew this, but Clouse always had a crush on you when you were students, he just never told you because he was a jerk.
