That smile is pretty obviously fake, but Sheena doesn't call him on it, just shooting him a small one of her own in return as he takes some of the food.

"Oh," she says. "About... what happened in Kilika? Or--" Hey, why is she asking this? She is curious about her guardian, someone who seems like a walking contradiction already, but he's right; this is a terrible way to get to know someone. She tries again: "Sorry. You don't have to answer that, we can talk about something else if you want." She takes a seat, back against the deck rail so that even if the breeze picks up, the rolling of the ship won't move her, and sets the rest of the food down in front of her.
