It looks as though Isidor didn't quite get the festive holiday memo. She is at the party, mostly at the behest of her future sister-in-law and to keep an eye on his brother. The grey ruched dress she wears is not exactly Yule wear, but her heart really isn't in it this year. After Halloween she's staying firmly away from the bar this time, which means being painfully sober as she avoids socialising.

She's found a nice little corner from which to keep an eye on Viatorus and stay out of the way of the more cheerful guests. Whether she manages to avoid socialising while keeping watch is another question entirely.
