I saved the latter half of your post, Tom, and will post it after the others get a chance to respond. I'll give Zoey a chance to reply to your question, and then let Jack finish his brief chat with security before we get to your spell.
I also think I need to clarify something.
The building on the left is Tabu, the one one the right is Belladonna's home (you can't see her home very well in this picture because of the bushes). That fence you see between the two buildings is the courtyard. You don't need to go inside Tabu to get to the courtyard. That sidewalk next to the red car is where Ashley collapsed.
