Lloyd and the ninjas were in your school

The ninjas started to go to your school. You and Lloyd became decently good friends, so he did trust you enough to tell you certain things, just not all of it

One certain day, when Lloyd stood up to go to the board, he felt dizzy and Kai notice this as he was sitting right behind him

Kai: Are you okay, Lloyd?

Kai asked, whispering

Lloyd: yeah, I'm fine...

He whispered back. The teacher didn't call up on him, but Lloyd only got worse
