"Steve Vs. Hayley The Dark One's Last Stand"

At the beginning:

The narrator says, "Previously on American Dad!" Steven says, "There maybe a way to find Jeff we go into the Underworld." Nimue says, "Once Steve brings us back it'll be game over for everyone." Matthew says, "Good news we found the portal bad news so did Steve." Back into the present: Matthew and Josh saw Steve used Steven's blood to open the portal to the Underworld once it was opened every Dark One showed up before Steve. Nimue came up to Dark Steve and said, "We're all very proud of you and now it's time to get to work to do what Dark Ones do best snuff out the light." Dark Steve says, "Let the chaos and destruction begin!" Head right to the theme song.

After the Theme Song:

Steven and Hayley ran as Steven was on the phone saying, "He did what?" Hayley says, "What's going on Steven?" Steven says, "We gotta head on down to the festival turns out your brother released every Dark One outta the Underworld." Hayley says, "You mean those people we saw in the Underworld?" Steven says, "Afraid so looks like we could be in for the fight of our lives!" Unfortunately they were too late and every Dark One started to infect almost everyone at the festival. Francine says, "Someone help us!" Steven and Hayley headed on over to where that screaming came from and found Rumplestillskin and Nimue surrounding Stan and Francine, Hayley then said, "Get away from them!" Nimue says, "Too late for that!" Rumple and Nimue passed right through them and they disappeared then Hayley said, "Mom, Dad are you both okay?" Francine says, "I think so sweetie!" Stan says, "What the (Bleep) just happen to us?" Steven says, "I think I know the answer to that check your wrists." Stan and Francine checked their wrists and Hayley said, "Oh no what is it?" Steven says, "They been marked by the ferryman of the Underworld, you see the Dark Ones have a temporary pass into this world like a tourist phrase the only way to stay is to trade places with living souls." Stan says, "You mean us?" Steven says, "Exactly and when the moon reaches it's peak the ferry from the Underworld will arrive and drag you both and everyone at the festival down there." Roger says, "Wow luckily for me I'm immune!" Stan says, "What makes you think you're going to survive?" Roger says, "Because I'm an alien Stan I'm immune to Dark One spirits!" Francine says, "Both of you stop it Steven is there a way to prevent this?" Steven says, "There is but Roger and I will have to go on this mission ourselves." Hayley says, "No way I'm going with you!" Steven says, "Hayley think about it what happens if me and Roger fail you might never see them again so use this time to say good-bye to them just in case." Steven dragged Roger and he said, "Come on Roger!" Roger says, "Wait don't I have a say in this come on!" Heading onto First Commercial!

After the First Commercial:

Steven and Roger were walking into the forest and Roger says, "Explain where are we going?" Steven says, "We're going to end this war!" Roger says, "And how are we gonna do that?" Steven says, "With this!" Steven pulls out Excalibur and Roger says, "How did you get the sword?" Steven says, "You don't need to know how all that matters is that we complete our mission no matter what!" Roger says, "What do you mean?" Steven says, "You see Roger the only way to prevent the Dark Ones from taking anyone is to kill the current Dark One!" Roger says, "So in other words we're out here to kill Steve?" Dark Steve says, "Don't even bother you two!" Roger says, "Steve please just stop this before this gets ugly and I mean literally!" Dark Steve says, "Too late my plan's already in motion and soon you'll bow down before us!" Steven says, "Steve I know you want your father's respect but this isn't the way to do it you're becoming the very thing he didn't want you to become." Dark Steve says, "And now because of that he gets to die!" Steven says, "No!" Steven charged in Dark Steve disappeared and re-appeared and Steven said, "I will protect your family even if I have to kill you to do it!"

Meanwhile back at the Smith House:

The Smith family spend a nice quiet dinner before Stan and Francine get dragged down into the Underworld and Francine accidentally discovered Steven's plan and said, "Stan you need to see this!" Stan says, "Oh no!" Francine says, "We have to fine Steve fast!" Stan and Francine moved and Nimue showed up and said, "There's no need to worry your son can take care of himself which means there's no way to stop your trip to the Underworld." Hayley came down with Klaus and saw her parents disappear and said, "Mom, Dad leave them alone!" Nimue says, "Sorry little girl but I'm afraid their required for our revival!" Nimue disappeared and Hayley ran off and Klaus says, "Aah what are you doing?" Hayley says, "Finishing what I should've started." Steven and Roger attack Dark Steve and he said, "Soon it'll be too late we have to attack from both directions!" Roger says, "Sorry to do this to you Steve!" Roger attacked and Dark Steve threw him and said, "Well I tried!" Dark Steve evil laughed and almost used Excalibur on Steven to finish him off but then Hayley swoop right in and saved him. Steven said, "Hayley!" Hayley says, "Didn't really think I was gonna lose you too did I?" Dark Steve struggles and Steven says, "Hurry use Excalibur to finish him off!" Hayley says, "But!" Steven says, "Now that we found the portal we can always bring him back do it!" Hayley says, "Smile you son of a bitch!" Hayley kills Dark Steve destroying all the Dark Ones. Steve turns back to normal before he died and Excalibur turned to dust. Steven got up and hugged Hayley tight as she said, "I hope you're right Steven I hope you're right!" Hayley started to cry heading to Second Commercial!

After the Second Commercial:

Steven, Roger, Klaus and Hayley arrived at the Portal to the Underworld where they saw her parents. Stan and Francine hugged it all out and Roger says, "Aw man I really wanted you gone!" Francine says, "Oh Hayley I was afraid we were gonna lose you by the way where's Steve?" Hayley cried and said, "He didn't make it!" Francine started to cry and said, "What?" Hayley says, "In order for Excalibur to take down the Dark Ones we had to kill the current host." Francine says, "Oh my god poor Steve!" Francine cried it out and Stan says, "There there he's in heaven now!" Francine in anger says, "Or in hell with the devil!" Steven says, "You're both wrong when a Dark One dies they get sent to the Underworld." Stan says, "And you know this how?" Steven says, "Because me and Hayley been there!" Stan and Francine said, "What?" Hayley says, "Well it was to rescue Jeff and I.." Francine says, "Hayley!" Stan says, "How could you do this?" Steven says, "It doesn't matter now that we found the portal to the Underworld we can go there and bring Steve back!" Francine says, "Is it possible?" Steven says, "Wouldn't had brought Hayley down here if I knew it was possible however you two will have to split your hearts with your boy to bring him back." A mysterious voice says, "I don't think so!" Stan says, "Who's there?" Debbie shows up outta nowhere and Francine said, "Debbie what are you doing here?" Debbie says, "Well I kind of overheard that Steve's in the Underworld so I figure I try to help him out!" Stan says, "Absolutely not!" Francine says, "Stan never mind him he's just mad at how much you broke our Stevie!" Debbie says, "Don't worry this time I'm gonna be right there with him!" Hayley says, "Sounds like true love to me!" Francine says, "Agree!" Stan pouted and said, "Fine!" Steven says, "All right let's get this show on the road!" Steven cut his hand with a knife and threw part of his blood into the water summoning the ferry to the Underworld Roll to the credits: Steven, Stan, Francine, Debbie, Hayley, Roger and Klaus enter the ferry and Hayley secretly says, "Jeff if you're still down there don't worry I'm coming to bring you back!"
