"We're working on episode four, which is exciting, [and] there is a flashback to the night of the particle accelerator explosion, from somebody else's perspective which we haven't seen before. It's a good one," Kreisberg said.

set to reprise his role of John Constantine on The CW series, Kreisberg praised the quasi-crossover episode. "I just read the script for five and it's unbelievable," he previewed. "You're going to be blown away." The episode will feature a resurrection, CW president Mark Pedowitz revealed to reporters at TCA, which is likely tied to the Lazarus Pit storyline.
