The latest generation of the Royal Flush gang, a dynasty of wealthy thieves using a card-playing motif, returns to Gotham. Meanwhile, Terry's commitments as Batman strain Terry's relationship with Dana to the breaking point -- so much so, he falls right into the arms of a new girl in town, Melanie Walker, who has her own problems with an overbearing father.
Melanie never learns about Terry's double life, but he learns about hers -- as Ten, the youngest, reluctant Royal Flush gang member. Olivia D'Abo, George Lazenby, Amanda Donohoe, and Scott Cleverdon make their first appearances as Ten, King, Queen, and Jack.
The official DC Animated Universe in a somewhat chronoligal order. Infos taken from all over the web. I tried to order some episodes differently, as you can see with Batman TAS' Two-Face 2 Parter - which is now seperated by a couple of episodes, as the second part states that there were 6 months between the events of the two.
