[D-8432, just as we agreed before. As long as you complete this experiment, I will submit an application to reinstate your status as a Class B researcher.]

D-8432 listened and responded quickly.

[I hope you can abide by your promise and agreement. I am not one of those D-class criminals. Don't treat me with them.]

[Of course, okay, pick up your camera and get ready to go]

Boom--boom--

Boom--boom--

, and then create a fourth experiment.
