[Sci-Ryan lands on the ground with Chloe]
Sci-Ryan: Hey, guys.
Odette: What are you doing?
Sci-Ryan: We just thought Rockset might show up at any moment.
Evil Ryan: Cool. Now that Sunset is akumatized, Bertram can't be her bodyguard.
Bertram T. Monkey: Hey! I was hurt about that.
Iago: Don't worry, you two. Megatron can be Starlight's bodygaurd.
Sci-Rianna: For now.
Spikewave: Go, Rockset! Go, Rockset! Go, Rockset, Remember!
Codylight Sparkle: WILL YOU KEEP IT DOWN?!
Sidecord: Yeah, you're hurting my audio-receptors.
Sci-Ryan: I have no idea why Rockset is famous. Chloe and I saw a video of Rockset singing that same song Ember sing at Amity Park.
Chloe: That's what makes her so awesome.
Bertram T. Monkey: You said it, Miss Chole.
[They suddenly hear music]

Dr. N. Brio: The wind blows, the dead leaves fall~ [laughs]
Rockset Shimmer: To you, I did surrender~
[Matau pulls Marrinette to a room]
Matau T. Monkey: I think we need to crash that concert, Marrinette.
Tikki: The talking monkey's right. I hope Ryan could do the same.
Marrinette: You're right, Tikki. I'll let Matau say my saying. [to Matau] What time is it?
Matau T. Monkey: Transforming time.
Marrinette: Tikki, Spots on!

So warm and tender~
Rockset, Brio and Cortex: You will remember (her) my name~
Rockset Shimmer: Hello, Collège Françoise Dupont! Tell us who you love!
Crowd: Rockset Shimmer! Rockset Shimmer!
Evil Ryan: Yoo hoo! Hey, everyone! Look! It's Rockset McLamer!
[Rockset's hair dims]
Rockset Shimmer: Oh great. A critic. Maybe the former follower of Unicron likes our new song better.
Evil Anna: Come on, Ladybug....
[Crash jumps onto the roof then Ladybug stands beside him]
Sci-Ryan: Look! It's Ladybug!
Crash Bandicoot: Right on time, Ladybug. I'll help you on this thing till Cat Noir arrive.
Rockset Shimmer: Bring it, Ladybug and... [to Crash] Bandicoot Boy?
Crash Bandicoot: Bandicoot Boy? Is that a hero ID or an insult?
Dr. Neo Cortex: It's an insult, stupid Bandicoot!
