Young Justice Episode 1.20 Coldhearted

November 11: Kid Flash is disappointed on his birthday when he is tasked by Batman to deliver a heart to Queen Perdita of Vlativa, while the rest of the team is sent to join the Justice League and destroy flying fortresses causing nationwide snowstorms. On the way he is attacked by Vandal Savage, who delays him for some time. Kid Flash reaches the hospital only to be informed by a doctor that Perdita already passed away and takes the heart from him. Kid Flash realizes he's been tricked, and stops the doctor, a henchmen of Count Vertigo (Perdita's uncle who plots to let her die and take the throne). Kid Flash manages to retrieve the heart and get it to the doctors. However, it is reported on the news that Perdita died during the operation.

November 12: Count Vertigo approaches Kid Flash in his hospital room and gloats over his success. It is revealed that Perdita is alive with Kid Flash having faked the news and tricked him into confessing. Perdita revokes Vertigo's diplomatic immunity and he is arrested. Perdita offers Count Vertigo's sword to Kid Flash as a souvenir.

November 13: At Mount Justice, it is shown that Wally kept the heart carrier instead having realized that saving Perdita's life was more meaningful. At Belle Reve, Hugo Strange meets Batman and Flash and explains that the five ice-powered villains (Batman's prime suspects of the fortresses) were apparently in their cells the whole time.
