Elizabeth makes note of the tomb to follow up on, later. Is there anything else of note that happens or does anyone particularly important come out from the building?
If not, Elizabeth wants to catalog her findings, to keep, and make a copy to turn in. She wants to include names and possibly locations of any of the widows coming and going as well as the location of the tomb. If she can, she'd like to get her best estimate at a count of unique people and ghouls coming and going to help estimate the size of the organization (or at least the size that moves about through the city).
At any point, does Elizabeth feel she's being watched or tailed? She wants to avoid turning into her human form in front of anyone.
