Steven POV.
It was morning and Steven was eating breakfast.
He suddenly start thinking about his mother: Rose Quartz. He asked Pearl about his mother then Pearl said "Well your mum was a great Gem she believed in everything and that it always had good in it and she had a room which is now yours cuz she's gone now".
Steven says "So since its mine how do I open it?" Pearl said "for the first time I actually dont know ask your Dad maybe she told him."
Steven went to the car wash in his scooter and his cheeseburger backpack. When he got there he asked his Dad "Dad do you know how to open mom's room?" Greg replied "Sorry son I don't know anything about that."
Steven went back to their house and he tried opening Rose's room with his bellybutton and after several tries he finally done it he opened it. Apparently it can make things appear for Steven as long as he keeps it simple or else everything would go wrong and malfunction.
So Steven called out Emerald and brought him there. They played there for hours not noticing the time. After that Emerald went home and they said their goodbyes and just went on their own paths.
