Soldier: All NS5's, report for service and storage. All NS5's, report for service and storage. All NS5's, report for service and storage.
[Spooner looks at his damaged robotic arm.]
Optimus: Brave warriors.... you are free!
[The Dinobots transform]
Cross-Hairs: I'll ride with you anytime, Spike!
Grimlock: ROAR!!!!! [he takes off with the other Dinobots]
Ash: Goodbye Grimlock, It's nice to see you again. [turns to Serena as she blushed] Serena?
Serena: Yes Ash.
Ash: I just... wanted to... say... Thank you, for saving my life. And for protecting me and my friends, helping us take down our enemies but mostly for saving my life.
Serena: You're welcome.
Ash: But why did you do all that? You've could've died.
Serena: Well, the truth is.. it's because I love you, Ash! And I don't want to lose you! NEVER EVER!! You're the one I've loved! And all I want is to you is to be more than a friend! That's the truth. I love you!! [kisses him on the lips]
Ash: [surprised what she said and did]
Serena: Ooo...what was I saying?!
Ash: It's okay Serena. When you and I first met, I started to like you, too. I know that you have feelings for me. And I;m happy to be alive.
Serena: So, will you be my boyfriend, Ash?
Ash; I sure will.
[the 2 then hug each other]
Max: Serena sure has huge feelings for Ash, huh?
Gordon: Yeah. She sure does.
Rini: I hope that Ash and Serena are going to be married.
Louis: They will, Rini. they will.
Calvin: One thing bothers me. Alfred was VIKI's prisoner. I don't understand why she would kill him. The last thing she would want is police snooping around.
Spooner: That's true. That's true. But then, VIKI didn't kill the old man. Did she, Sonny?
Sonny: No. He said I had to promise.
Brian: Promise to do what?
Sonny: Promise to do one favor for him. He made me swear, before he'd tell me what it is he wanted me to do. He made me swear.
Carver: Wow, I didn't realize that.
Godou: Me either.
Ash: But we've save the Earth.
Delia: I suppose my son is right.
Shido: And we destroyed VIKI once and for all.
Spooner: Then he told you to kill him?
Sonny: He said it was what I was made for.
Eddy: So that means...
Calvin: His suicide was the only message he could send to you.
Blossom: Of course!
Spooner: First bread crumb. The only thing VIKI couldn't control. Lanning was counting on my prejudice to lead me right you.
Sonny: Are you going to arrest me, detective?
Spooner: Well, the DA defines murder as one human killing another so...technically, you can't commit murder, can you?
Sonny: Does this... make us friends?
[Spooner held his hand to him. Sonny grabs and shakes his hand]
Calvin: Something up here after all
Spooner: For him.
Optimus: Detective Del Spooner, meet Godou and Liliana's child, Hodou Kusanagi.
Spooner: [looks at Hodou] Congraduations, now you can keep him save.
Liliana: We will.
Lita: Norville...ur..eh...I mean...... Shaggy. Thanks for saving me.
Shaggy: You're welcome.
Lita: You know that I really really love you. Maybe we can go on a date together.
Lita: Oh Shaggy, I love you.
[Lita and Shaggy share a kiss]
Shaggy: I love you, too Lita.
[Lita and Shaggy also share a hug]
Erica: Why so down, Tino?
Tino: It's Starlight Glimmer.
Ena: Why did you say her name?
Tino: It just something that she said.
Mana: Come on Tino, you know that she's dead.
Misty: Yeah, Optimus Prime killed her to save you and Ash.
Tino: I know but... she said something about my past, like where I'd came from, who I really was, and about my real self. And I want to know what it was about my past.
Cross-Hairs: Why would Starlight Glimmer know about your past.
Tino: I don't know. But I need some answers.
Sunset Shimmer: My boyfriend. That's who you are, Tino. And you will always be my boyfriend, no matter where you came from.
Tino: Thank you Sunset. That means a lot.
Godou: What's up with you Shido?
Shido: It's Kurumi's last words.
[Brian drives the sword into Kurumi's stomach]
Kurumi: I love you... Shido. [dies]
Shido: She said that she loves me.
Knuckles: Impossible! The real Kurumi never loves Shido, never!
Shido: Well, she does love me.
Willy: How did you know.
Shido: Because I've save her, using myself as her shield.
Ash: Oh yeah, I'd remember. [flashback starts] Shido was trying to save Kurumi from Kotori when she wasn't herself, that kind of spirit power inside Kotori must have turned her evil and can't control it. [flashback ends]
Carver: Besides, we were there when it all happened.
Sonic: Wow, I didn't realize that.
Princess Luna: Me either.
Bumblebee: Come on! Let's forget about Kurumi and move on.
Rattlesnake Jake: He's right you know.
Shido: Okay. I understand.
Soldier: All NS5's, report for service and storage.
Sonny: What about the others? Can I help them? [Cut to him in the Lake Michigan, walking on the sand]Now that I have fulfilled my purpose. I don't know what to do.
Spooner: I guess you'll have to find your way like the rest of us, Sonny. I think that's what Dr. Lanning would have wanted. That's what it means to be free.
Soldier: All NS5's, proceed as instructed. All NS5's, proceed as instructed.
[The NS-5's looked at Sonny]
[Back with Patchy]
Patchy: Ahoy, children! I'm back! I hope all you boys and girls enjoyed the show because it's time for you to walk the plank! [Screen reads: PLEASE STAND BY] Oh, sorry, kids. What I meant to say was it's time for fan mail! [blows horn]
Old-time crowd: Hooray!
Patchy: And now, the moment you've all been waiting for, so get ready to blow milk out of your nose because we're gonna open a letter! The envelope please Potty. Thank you, my fine feathered assistant.
Potty: [Potty has a lighten fuse on his head] Brawk, you're not welcome.
Patchy: [Patchy blows his nose] Hey, Potty, do you smell something? Oh, Potty! That fuse in your head! I told you we're not doing that stunt!
Potty: Brawk, I didn't get the memo! Brawk! [Potty blows up along with Patchy; Patchy coughs up a feather and recovers from the blast]
Patchy: Well, thanks for watching "Weekenders Adventures of I, Robot". Hooray! [Potty collapses to the floor] And stay toned for the Weekenders and friends’ Amazing Explorations movie Starlight Glimmer's Return. See ya!
[The movie ends with Calvin Harris - Outside ft. Ellie Goulding]
