Imagine an Adrigaminette reveal scenario
Except Kagami already knows and is trying to get the other two to come clean so they can put the identity shenanigans behind them. She’s got it all planned out how she’s going to feign being surprised and everything. She butters them both up about how they should be on even footing and no more secrets and she’s almost giddy because it’s about to happen...
And then, her two adorable little idiots go and reveal that they are Multimouse and Aspik and they’re the ones faking surprise at each other and she’s just like “who the hell are those?” And “Are you making these up”
And now they’re on a superhero date because ‘Multimouse convinced Ladybug’ and Ryuuko’s just at the center of a cuddle pile wondering how this happened
