After parting ways with Carly Stratmann, Annie wants to have one more donut before her day is done.

Summary
Thinking back on her busy day in her search for Carly Stratmann, Annie decides that before she heads back to the Military Police barracks, she wants to have a donut one more time.

Taking Carly's direction and time elapsed when she went to buy a donut earlier that night, Annie calculates the approximate location in Stohess District where the donut shop must be located. Upon remembering seeing a seed from a specific waterside plant on Carly's skirt, she heads for the precise location. However, she finds that the donut shop is closed. She sits in defeat, and an older woman, the owner of the donut shop, spots her. She asks about Annie's behavior and offers her the last donut of the day before heading off. Annie accepts it gratefully and eats it by herself, appreciating the sweet taste.
