I noticed something last night, in the scene where they all meet at Tony's house after his Mother dies and they have her service, if you notice when Janice starts asking everyone to say something and it cuts to Tony, if you pay attention to the background someone walks down the stairs, looks and then walks back up the stairs. Who would be upstairs in Tony's house? Both kids were downstairs with everyone gathered talking about Tony's mother.

I wonder if it was an extra or some worker of if that was planned?
