There's a cushion like object sealed in plastic like for storage. The curtain for the stage is behind the viewer with the other wall to the off stage entrance behind and to the right of the viewer. The speaker is aiming diagonally to the left and towards the view a little while the sink and mirror are to the right. So she is on the right most edge of the stage or just off stage. The sink is to help people get ready for or clean the sweat off from being up on stage. So she isn't the main focus of the event, which is occurring on the stage proper, but is performing some sort of supplementary performance. If the main act is a speech then she could be a translator. If its a play or something then she could be a narrator. Otherwise she could be singing... Whatever it is the main act needs. I suppose the photographer decided to focus their own spot light on this person who would normally be out of it?
Best guesses I have. *shrugs*
Whatever she is doing she is not in a bathroom! XP XD
