What did Barbara Poelle leave at the bar last night? **UPDATED

A great time was had by all, particularly the ever-slithery Barbara Poelle, agent extraordinaire (and by extraordinaire I mean Potato Vodka Queen of the Known Universe)

Sadly Barbara forgot an item at the party. She texted us to ask us to hang on to it if we found it.

What did Barbara lose?

Was it A: her tiara?

Was it B: the keys to her dungeon manuscript reading room?

Was it C: her pink sombrero?

Was it D: her own version of BossyPants?

Was it E: her date for the evening?***

***Barbara telexed from her hideout an undisclosed location to let me know the date did not quite as well as she'd hoped:

Was it E: All of the above?

Was it F: none of the above?
