Everyone was already gathered waiting for Astrid to speak to them. When Jake, Rachel, and Haley got back to the coven, his father has already contacted Glory requesting another meeting. So Glory asked them to reach out to their vampire friends, but they assured the witch that there is no need since they know Enzo would make sure to drag his people to the coven since the Queen already ordered it.
After everyone gathered, they were hoping to see Alex but Astrid was the one that came. Though they never expected her, they still have her the respect she needed. Something in them told them that disrespecting her would be a crime punishable by death.
