Knuckles, Chris and others in “Unfinished Business”

Knuckles

[about the device that the Metarex planted inside Cosmo's head] Can we stop it?

Chris

I'm not sure. If we do she won't be the same. The signal is controlling her sight and hearing. If we remove it she may not be able to hear or see again.

Knuckles

[Growls] Then that's a chance we have to take.

How can you say that?! I'm not letting anyone hurt Cosmo!

Knuckles

We don't want to hurt her. We just want to set her free, and if she has to lose her eyes and ears, then so be it!

There has to be another way!
