Should your character have an emergency at a late hour, Herr Antonius regularly takes the evening and night shift to ensure that someone's in the infirmary even when Ania is asleep.
If you would like to encounter him, you can contact me in the following ways, either for an OOC settlement or to arrange a scene:
Whisper ALCHEMIST on Furcadia, or
look for HERR ANTONIUS in the Eileadora Discord (http://eileadora.com/index.php?topic=1334.0). (Feel free to tag or DM me for my attention.)
