Bunny (Event 1: First Corruption)

"Bunny has been occasionally texting me about her worries of Lyra's behavior and asking me to try to find out stuff from my end. After waiting for a bit to make it seem like I was actually investigating anything, I went of to Bunny's place to share what I had."

Bunny was extremely happy for me to finally claim to have something to help her figure out what's happening. She got us both drinks and run to her room to grab the list of strange behaviors she noticed from Lyra.

As soon as left the room is quickly poured the serum into her drink and pocketed the used vial.

Bunny came back and immediately launched into talking, about Lyra's changes and all but begging you to help her get to the bottom of this. In the middle of this she took and sip of her drink that turned into downing her drink and falling under the serums haze.

"Obviously the easiest way to corrupt bunny is to use her love of Lyra against her." You thought

Show her what's happening to Lyra is a good thing and turn her into a bimbo too

Or

Reveal to her your the one corrupting Lyra and blackmail her into obedience for you to leave Lyra alone
