The final arc of "The Flash: The Fastest Man Alive", "Full Throttle", features the Rogues successfully killing Bart Allen, the fourth Flash. Within "Countdown", both the buildup to this as well as its aftermath is felt. Bart's funeral is held and Piper and Trickster are forced on the run from superheroes and villains alike, which also ties into the upcoming "Salvation Run". Connecting this story to "The Lightning Saga" is Wally's return to Earth. Wally's new vendetta against the Rogues is witnessed in "Countdown" where he finally catches up to Piper and Trickster, the remaining Rogues having already been captured in "All Flash" #1.
