Episode 20: Coldhearted
Takes place on November 11 - 13
When mysterious machines cause a snowstorm across the United States, the team must work with their Justice League mentors to stop them. Except Kid Flash, who is given the mission of delivering a human heart for an urgent transplant. He's annoyed at missing the team-up, until he finds out that some supervillains want to prevent the transplant for some reason. (The girl being operated is the rightful queen of Vlatava, an European country, and her evil uncle Count Vertigo wants the throne.)
Notes:
- Key characters in the episode appear in the DC Showcase: Green Arrow short film, and the same voice actors reprise their roles.
- We learn that November 11 is Kid Flash's birthday.
- Where and how Vertigo got the snow machines is left a mystery. (Though it's implied the captured ice villains were involved and that Hugo Strange covered for them in Belle Reve.)
- The premise of Wally transporting a heart through a snowstorm on his birthday and encountering Vandal Savage comes from the comic The Flash (vol. 3) #1, the first issue of Wally's tenure as The Flash.
- Billy Needs an Organ: The main plot of the episode is that Kid Flash has to deliver a donator heart to help save the life of the young Queen Perdita.
- Diplomatic Impunity: Count Vertigo was able to use this to his advantage to avoid imprisonment after the Injustice League incident previously. He attempts to use it again when he thinks Perdita is dead only for Wally to reveal that she's alive and sitting in the bed right next to him. She promptly revokes his diplomatic immunity and places him under arrest for trying to indirectly kill her.
- Engineered Public Confession: Wally manages to trick Count Vertigo into revealing his part in attempting to indirectly kill Perdita by delaying her heart transplant to Perdita herself who promptly places him under arrest.
- Product Delivery Ordeal: The episode revolves around Kid Flash having to run all the way across the United States (from Boston to Seattle) to make an emergency delivery of a donor heart for Queen Perdita of Vlatava, who will die without the transplant. Along the way, he has to evade the allies of her villainous uncle Count Werner Vertigo, who wants Queen Perdita to die so that he can claim the throne of Vlatava for himself.
- Race Against the Clock: Kid Flash has to transport the donator heart 3000 miles (4800km) across the country before it's no longer viable in four hours.
