Katara is completely blown away by Star's abilities, and generally pleased with her positive outlook on things. She's glad to meet a friend of Beastboy's at any time, but Starfire is definitely someone she would have sought out eventually.

Billy is still one of Katara's closest friends on the ship, and someone she looks out for. To her his worse trait is his occasional lack of self confidence, something she hopes to get him out of. After that episode with the exchange of emotions, she feels even closer to him.
