Plagg: Duusu?! Why is Duusu here???
Duusu: Plagg, is that you??? It has been so long since I've seen you!
Plagg: Wait, don't tell me Nooro is here too. How did the Guardian managed up this coincidence?! I should-
Adrien: Wait, I know this looks bad and before you try destroying everyone, what do you feel about neutral chaos so we can all get what we want including a lifetime supply of the finest cheese for you...?
Plagg: ... I'm listening.
Adrien: [Explains honestly to little kitten as the pure sunshine boy he is about how he does not advocate for his father, wants to save his mother and have a family of whole and the only 'evil' thing he might resort to would be painless, fun and chaotic anime renditions such as Pokemon and Persona 5 and not giving the Guardian a great time because his mother's state is due to a certain Guardian's 'mistake'.]
Plagg: Hmm... we will give this a trial run but I reserve the right to take away my Miraculous as I see fit. You would not want to face the Wrath of Destruction, would you?
Adrien: No, sir.
Plagg: Ehh, don't be that formal... just call me Plagg.

Adrien: Plagg, what are- these are adoption papers! Again?!
Plagg: Yeah, who needs that stick of a mud when you can call me- wait, again???
Duusu: Wait, Adrien, if you are going to sign those papers, why didn't you sign mine first???
Plagg: Wait, this kitten is mine!
Duusu: He's my chick first!
Adrien: Guys...
