As always, I don't own TMNT.

Again, this is a short chapter but a lot of stuff is revealed in this one!

Karai leaned back in her chair in shock. That…is Raph's darkest fear? His own anger? Does he really think I would force Leo to take my place? Would I? Karai sighed and placed her head in her hands. First, I find out that Mikey's deepest fear is betrayal and Donnie's is his loved ones dying. Now this…maybe…making them breathe in the fear gas and hooking them up to machines that gave me the ability to see their hallucinations wasn't a good idea after all. Karai lifted up her head and slam her fist down on the table. No…it's still a wonderful idea! They deserve to suffer! Leo betrayed me! Their Father killed Mother! With a determined face, Karai turned on the intercom.

"Xever, give Leo the final stimulant and ring up his hallucination here asap."

"Yes Mistress." Karai leaned back in her chair in fierce anticipation. Now Leo, what is your worst fear? She then pushed the remote connected to the T.V. in front of her without any hesitation.

Sorry if the whole techno/science info was not that specific. I am not an expert in that area so I didn't know how to really describe it. Please review!
