Red-Eyed and Blue-Tailed

Do you think these two are under Nightmouth's mind control? 

You wish to show them mercy, don't you?

I told you, I don't want to kill anybody else if I don't have to.

Well, why don't you ask them whether or not they want to go? Im thinking back to that temple Priest who had us all convinced of his innocence. 

I dispensed with caution and strolled towards them. 'I heard you're looking for me. I'm prepared to offer you one chance, renounce your master and escape to freedom.'

They both laughed in my face, giving me the only answer I needed.

Laugh at this. 'Aquatic Slingshot!'
