I thought they were just some normal feathers! But this is... it's like a Devil's Fruit power. [Making memories into feathers... yeah, definitely sounds like it could be a fruit power, even though it's this "magic".]
You'd take them? [Of course she'll trust them with you, she doesn't really know anyone else here well enough yet to give them any of her memories-- even though the other memory she has, one of her first meeting with Luffy, is more amusing than anything else.]
