If you've watched today's episode and saw the end your probably like 

Nooo Garroth don't die!

He's not going to die! Geez! 

Aphmau didn't kill off Laurence because he is major to the plot, Garroth is to so she probably won't kill him off and here's how I think next episode begging will go,

Garroth: Aphmau! Aphmau! Where are you?

Aphmau finds herself in the dream dimension(I have no idea what that place is called so dream dimension)

Aphmau: Garroth I'm her- ARE YOU OK!

Garroth: Aphmau, help me...

Aphmau: Nononono this can't be happening!

Aphmau heals Garroth

Garroth: !?!

Bells ring

Aphmau wakes up

Aphmau: I need to get him out of there!

So yeah he can't die because she can heal him, so calm down and stop ranting about his death he is going to be alright 

Cat out!
