I think that was before she died, right?
That was a different time, just the utilities. The night she died or the day after, they also changed the locks, then HKS threatened somebody and played the baby card and they switched the locks back to the keys ANS had originally.
Then there was a court order that they could change them again, but BT/FS said they'd give HKS time to get his ducks in a row so that the baby is taken care of, then he has to be out by March 14th.
