"NO!" Joker shrieked, highly agitated. "You're supposed to die! You are a SPOILSPORT you great winged freak! JUST FUCKING DIE!!!!!" and with that the Joker hurled what looked like an overripe plum at Batman's feet. With Batman to one side of him and Vicki to the other it felt like quite the interesting pickle to the fiendish clown, now downright demonic in the pall of noxious purple smoke emanating from the bomb. "Laughing gas, Batman! My own special blend in fact! Sorry if it comes on a little strong but well, I think that's the point!" Joker stared at Vicki, beginning to gasp and choke, and gave her a consoling pat on the head as he dashed by her. "If it helps consider it a service... If you're gonna go out, do it with a smile on your face!" With that the Joker tripped a remote in one of his many pockets and swung through a suddenly revolving heavy steel door set in the back wall. As it settled back on its pivot the slam of bolts permanently locking it into place could be heard... It was an echoing thud-thump-thump that mingled well with the horrific crash of a heavy steel plate slamming down through the entrance of the utility room. They were sealed in.
