Here's the purrevious part:
Ladybug stood up. She remembered the time she almost have up once. How Chat Noir wiped away her tears. She missed that feeling. She missed the feel of his gently hand, or paw. She looked at the ring, which was still black and green. She gently brushed the paw on it with her finger.
As she did, the ring suddenly turned silver, and a tiny black kwami popped out. Plagg. He flew out and landed on the ground in front of Ladybug.
Ladybug: Plagg! Are you alright?
Plagg: I.... I'm fine.... What.. what happened? Where's Adr- I mean, Chat Noir???
Ladybug: *more tears* In.... in there *points to acidic cauldron*
Plagg: No!!! NO NO NO! IT CAN'T BE! *flies over and looks in* No.... kid..... *floats down* He's..... *looks up at Ladybug, crying black*
Ladybug: *holds Plagg gently* Yes..... *hugs Plagg*
The two mourn together for a moment. Plagg was the first to snap back.
Plagg: Should I tell you?
Ladybug: Tell me what? *sniffle*
Plagg: His identity. We have to set it straight. Otherwise people will wonder what happened to him.
Ladybug: ............. There's no other choice. Yes. Who is he?
Plagg: Please forgive me, Marinette. Chat Noir..... is..... Adrien. Adrien Agreste....
Ladybug: *shock and grief* WHAT?? No, no, no!! It can't be!! *shaken sobs* Nooo! Not him... not them!! *more tears stream down*
Plagg: Forgive me, Tikki. *more black tears*
Surprisingly, Ladybug's earrings also become moist. A pink liquid drop comes out of the left earring.
Plagg: I'm sorry, Tikki. *bows head*
More tears are shed, but Plagg's tears were black, like liquid ashes and rust. Tears of the kwami of destruction were naturally of destruction. He was careful not to let the tears touch Ladybug's hand. Some fell on the ground. The grass was wilted where his tears touched it. Plagg was able to fly right. He flew up to Ladybug's face and wiped his tears away.
Plagg: Enough. We have to stop Hawk Moth! That's what Adrien would have said. He wouldn't want us to waste any time! We can't bring him back, but we can avenge him. Marinette. Detransform.
Ladybug: Spots off. *detransforms*
Tikki flies out and floats next to Plagg.
Tikki: I heard everything...
