Albus seemed to find the room of requirement with slight difficulty. He blamed this on twenty-three years of hallways moving around on him, or perhaps it was just his rubbish sense of direction. He couldn't figure out whether meeting a girl for tea counted as a date, and so he had tried to appear reasonably nice -- without overdoing it. This particularly involved combing his hair, which never stayed flat unless he did something drastic (like glue it down)
Passing the wall to the room of requirement, he saw the door. He expected this meant that Emma had already arrived, or someone else was using the room for something. Either way, it would be a lovely adventure and so Albus opened the door to see a table, a tea tray, and Emma -- or who he assumed to be Emma as he had never really spoken to the girl before outside of the journals.
"Hello?" The word sounded far too timid, and so he added. "It's a lovely day for tea, isn't it?" He offered her a seat at the table before sitting himself.
