everyone except bart is trying too hard to think of a way in that won't trip the security system. However bart, being as simple as he is, suggests that they go through the ventilation system. Lisa at first ridicules how cliche Bart's idea is but eventually he figuratively twists her arm into trying his plan. It works and they eventually make their way to the testing chamber where Isabella was moved to from the cell block. Kang and kodos attempt to shoot Isabella with the ray until bart shouts 'leave her alone!' and jumps in the way of the shot and mutates into a monster. This causes phineas to say 'Lisa we need to grab Isabella and get out of here before your brother hurt us!' Lisa objects to this 'but it's bart I can't just leave him.' phineas promises her 'we'll find a way to save him later but we can't while we're in his crosshairs!' Lisa eventually accepts this and says 'fine! don't worry bart we'll come back for you!' 3 hours later phineas manages to create a liquid antidote to the ray's effects. He then says 'I dipped a non fatal crossbow arrow in this antidote i whipped up. Here's the plan, rachel Abigail and i will keep bart busy. When I give the signal, Lisa, you will shoot bart with the crossbow arrow coated in the antidote.' after a few minutes of phineas, Abigail and Rachel stalling bart, phineas yells 'Lisa, Now!' before shooting the arrow Lisa says aloud to herself 'I'm sorry bart but this is the only way to change you back to normal. ' she shoots the arrow and bart goes from being a yellow mix between a troll and an ogre to his normal form. he says 'phineas, rachel, Abigail thanks for not punching or kicking me and Lisa, thanks for returning me to myself. you guys get out of here I'll handle kang and kodos myself!' after bart beats the snot out of kang and kodos and everyone returns to 742 evergreen terrace, Isabella says 'phineas, Rachel, Abigail, lisa thanks for saving my life. and bart, thanks for taking that blast for me.' Lisa replaces the ingredients Isabella dropped when she was kidnapped, the Flynn family returns home, and everyone eats the eggplant and chicken mix parmesan dinner Isabella was planning at the start of the story. the end
