I'd probably still act like myself with a name change. I don't know how to do a role reversal...
So it turns out in this stupid play this weekend, i'm not moving props, but instead shining a flashlight back and forth so people can make their way back stage quickly and quietly. I'm just doing this to see friends I normally never see.
Also for the two Sundays after this weekend, I have band events so that'll be great. :)
Once you give a Pokemon a personality, you can't go back depending on the severity and purpose of it. It's no longer just a "pixel" in your box.
