WWDD: S1E11 “OUT OF MIND, OUT OF SIGHT”
Dawn is in the kitchen mixing different varieties of cereal into a single bowl. Walking to the fridge for milk, she passes Buffy’s bag on the floor and does a double-take. A pointy piece of wood? A literal mace?! The items make Dawn think of the gigantic container of communion wafers in that old chest in Buffy's room…
At school, Dawn notices a short girl in her class—Melinda—for the first time. Melinda also lives on Revello Drive. Melinda is hanging around Kirstie and her friends, who vacillate between ignoring her and talking about her like she's not even there. A rejected Melinda sulks toward the bathroom, and Dawn—who's been in Melinda’s shoes—follows but discovers no one's inside!
That night, Buffy reminisces with Dawn about winning Spring Fling Queen in LA. Dawn tells Buffy about Melinda disappearing and can tell Buffy’s interested. The next day, Dawn spots Melinda sitting alone at lunch. She starts walking over to her, but Melinda disappears before her very eyes. In class, Dawn again sees Melinda and finally gets to talk to her. Melinda confesses she thinks she's disappearing, so Dawn agrees to help her. They spend the rest of the day together waiting for her to disappear, but it never happens.
When Dawn gets home, Buffy is out late helping her friend Cordelia with her May Queen dress. She darts upstairs to Buffy’s room, confirms the coast is clear and sneaks behind Buffy’s closed door. Just as she lifts up the false top on the old chest, the front door opens and Buffy’s home. Buffy checks on Dawn before bed, asking her again about the girl who disappeared in the bathroom. Dawn explains she must have been seeing things but tells Buffy how she spent the day with her new friend and neighbor. Buffy tells Dawn that she’s glad she reached out to Melinda. When she’s sure Buffy’s gone, she pulls out the diary she was concealing under the blankets and cracks it open...
