It isn't that hard to track down Alicia from the diabolism committee. She isn't a Shelynite cleric, but she's a sincere devotee and sings with them, so the temple of Shelyn is a good place to find her.
As for the why: Liushna is PRETTY sure Alicia is a song-sorceress and not a cleric or a shaman or anything, and there are things that song-sorcerers and shalyene usually have in common that apparently Alicia and now Liushna do not. Liushna is not confident Alicia will know what's up, but Alicia is firmly on Team Valia so she's got to be a reasonable human instead of a garbage human, these being the primary categories of importance when it comes to humans.
So: Liushna, in the temple, wearing the baby, looking around for her fellow delegate.
