"it could be. Madame 's got a gallery somewhere filled with stuff by students from when they were tiny. Suppose two people come up and say they're in love. She can find the art they've done over years and years. She can see if they go. If they match. Don't forget, Kath, what she's got reveals our souls. She could decide for herself what's a good match and what's just a stupid crush."
A passage form Never Let Me Go. Does it means if they(the Madame people) can go to check the arts? or if they(the lovers) are really in love?
