When I drew this, the scene popped into my head of Egon actually wanting to know what it was like to go into the trap. I never meant to imply that they'd stick him in the containment unit with the other ghosts ;P. He's smiling and saying good-bye like "no... it's fine, guys. I'll be fine!" More importantly, I was just sad today after finding out that Harold is gone. I just wanted to draw something in tribute to him and this is what popped in to my head.
