Mementos of a Lost Son is a quest in Xenoblade Chronicles. This quest can be received from Cheryl, northeast of the Commercial District, once Tephra Cave is accessible after the Mechon attack Colony 9. If Reyn is in the active party, he will comment and tell Cheryl she can count on him.
- "Find Cheryl's son's armour."
- Hint: Tephra Cave, near the dead merchants
- "Find Cheryl's son's gun."
- "Find Cheryl's son's knife."
- "Return to Cheryl."
"Cheryl now has some keepsakes of her son. They will serve to ease her pain a little."
Upon completion of this quest, the Affinity Chart will change if the following people are spoken to:
- Reyn: "You can count on me, lady!"
- Cheryl: "Hmm… is that so?"
- Reyn: "Do I look like someone who'd make jokes?"
- Cheryl: "It's nice to see there are still fine upstanding youths in the world. You remind me of my son."
