Biscuits for a Grandson is a quest in Xenoblade Chronicles. It can be received from Marcia near the shop in the Commercial District of Colony 9. After this and An Errand for the Heropon are completed, Zukazu may offer another quest, A Big Brother's Fight. If Fiora is in the active party, she will comment.
- "Take Marcia's Biscuits to Jiroque."
- "Return to Marcia."
"Jiroque has his grandmother's biscuits. What will happen when he fights his brother...?"
- Upon completion of this quest, an affinity link will be established:
- Fiora: "Why do you want the younger one to win? They're both family."
- Marcia: "Oh, that's right, Fiora... You wouldn't know. Anyway, that's our business. I shouldn't have said anything."
