I went back to read the locked-but-now-visible entries again, and realized something I'd managed to overlook before. Or, I had sort of realized it, but not let the full impact hit me.
Hafs is "rewarding herself" by letting Daphne come visit in May. It's her one-year anniversary in Idlewood. It's also the day before Daphne's birthday. Which means that the whole thing with Hafs went down the day before Daphne's birthday.
I double-checked. Unicorn Evils
plays out over May 12-14. This entry
from 2008 confirms Daphne's birthday as May 15th.
.... She very nearly lost both Hafs and Chaz - her family
- the day before her birthday. She did
lose her sister, in the sense of not being able to see or talk to her.
