Leonardo, April and others in “Unfinished Business”

Are you sure this is a good idea, Donnie?

Yeah. Last time you hooked me up to this thing, it made me blind and mentally connected to a giant fish-bird-worm thing.

Don't worry. I've upgraded it since then. It's perfectly safe. I promise. Your psychic powers have been advancing rapidly since you were given that Aeon crystal. It's imperative I test its limits. For your own sake.

I have it under control. Besides if it weren't for my powers, we never would have gotten away from Super Shredder. You saw what I did to that mutated freak.

That's what worries us.

I just need to examine your Crystal.

[firmly] No! I'm not taking it off! Don't even ask again, Donnie! It's safe as long as I have it!

If I can replicate how this crystal increases your powers, that could provide a frame of reference–

Increase her powers?

Don't worry. Only slightly by maybe .3%. April, let me know if you feel anything. OK? Tingling, headache.

I told you! I'm fine! Just leave the Crystal– AGHH!!
