Roxas likes her and is relieved to see that she's an extrovert. Emerald sure could use some! He's had a little trouble bonding with new Emeralds since Glass got Booked, but her being adamant about him not leaving when he Legacied went a fair way toward bridging that gap. He's gonna go out of his way to talk to her and bond now. (He wanted that already, but now it's more emphatic.)

Reverse?
