"Optimism is another word for hope, and I prefer to live with hope." There's a sense of relief when Damian takes the medicine. He's never liked to see children suffer, and although he does seem capable and fully able to make good on that threat, Enjolras can't help but be slightly amused by it. At least the children he'd met here hadn't given up. "I don't doubt that you will. Do you need water? I believe I have some of that as well."
