Theeka and Sosael, exchanged.

For those who didn't hang around Puzzlebox: Theeka is a hypersubmissive rubber mouse, who's had her negative emotions turned off; she's the leader of the Bubble Dolls, a clade of happy latexy servile types. Sosael is a hateful white butterfly who dies a lot, and may or may not be a face of the overall consciousness of the Strangevirus, a bio/data plague that infests an entire sector of the world. Sometimes they claim to be sisters, sometimes they deny it.

I played Sosael.
