The four of them were in Richard's room doing nothing, they were busy with themselves. While waiting for dinner, Richard, Nicholas, Roran, and Ethan were silent in Richard's room.
They sat in different places, Richard was playing games on the sofa, and Nicholas was laying on Richard's super soft bed.
Roran sat at the broken window in Richard's room, he looked out the window at the slightly overcast sky. As for Ethan, he paced in Richard's room to check all the items in Richard's room. Starting from books, photos, balls, wardrobe, and some boxes under Richard's mattress.
He didn't know what he was looking for, because when he was pacing, it was as if his eyes were taking up all corners of the room. The only one who focused on looking in the direction where Ethan was was Nicholas because he was secretly watching what Ethan was doing.
