Sabrina didn't end up making it on Saturday because she was out trying to help out with the Nightmares/Revenants. She'd have let the Geliara coven know that was going to be the case when she filled in the covens on what was happening in the woods after Atreus' initial post about the monsters from his world.
On Sunday, she brought some peppermint bark to share and chatted with her Geliara coven friends that she knows from school and have some conversations with her teachers that are there as well. She happily participated in the full moon ceremony and was respectful and courteous.
