This episode confirms Hawkgirl and Green Lantern's relationship in liking each other and it's fantastic. In the previous episode, we saw Green Lantern getting hurt and Hawkgirl worrying about him and expressing her feelings to him, so this episode beautifully wraps up the tension between them. Also, the Joker plot ties up reasonably well. I expected more, but I enjoyed the mind control plot joker had. I wish there was more to it since it was a very nice plot and I wanted more from it. Overall, it's a fantastic episode, and Joker delivers an outstanding performance. The royal flush gang makes an appearance. The last time I saw them was in Batman Beyond, so I'm not sure if it's a fan service moment or if we'll see them again in future episodes.
