They meet back up with Cat Noir

The two heroes headed out through the window while Ladybug briefed Polymouse on the Akuma and Sentimonster they were facing. "This Sentimonster has the power to multiply itself, and now, Dark Cupid has an army of archers at his disposal. I need you to serve as our backup. Understand?" Ladybug asked, to which Polymouse gave a hesitant nod, still suckling on her Miraculous/pacifier.

Just as they were approaching the scene of the conflict, they saw Cat Noir was doing his best to hold down the fort, but was still very much overwhelmed by dodging all the arrows. Cat Noir had found cover on a rooftop before he saw Ladybug and Polymouse, causing him to gesture to the two to come over to where he was. "It's a good thing you got back so quickly, Ladybug. I'm surprised we only need one hero this time." He said.

"Come on, kitty. You know what Polymouse can do." Ladybug smirked. "Have you used your Cataclysm yet?"

Cat Noir shoot his head. "It's ready to go. Got a plan yet?"

"Let's just see what I get from my... LUCKY CHARM!" Holding her yo-yo in the air, Ladybug used her power to create... a pair of water wings. Thinking for a second, Ladybug noticed they were still near a river, which gave her an idea. "We need to get Dark Cupid into the water."
