Oz: "A gift, in honor of your debut. This belonged to my grandmother, Serena from Irkutsk. A decorated war hero."
May: "Your grandmother?"
Oz: "Yes, she was killed in battle. Poor thing."
May: "Which battle?"
Oz: "Which battle? There were so many. You've heard of the battle of Kerplach?"
May: "No."
Oz: "No? Good. That's where she died."
