• Barry Allen has to face himself after the Crisis
  • Iris and Central Citizen are investigating Maelstrom
  • Diggle meets Barry after Oliver's death

After the winter hiatus, 'The Flash' Season 6 is set to return with episode 10. The characters will pick things from the Crisis saga and Oliver Queen’s (Stephen Amell) sad demise. Barry Allen has a lot of self-reflection to do as he mourns the death of Oliver.

Showrunner Eric Wallace spoke with TV Guide and revealed that Barry is ready to enjoy life and is happy he got a second chance. But there is a bit of survivor guilt as Oliver could not survive the crisis. Only Barry survived and it is going to trouble him forever.

Meanwhile, Diggle (David Ramsey) would meet Barry in episode 10. Diggle knows the pain of losing a partner and he will comfort Barry in his time of need.

As Barry discovers his second life after Crisis, Iris (Candice Patton) will be on a mission to uncover a dangerous organization. Iris and the Central Citizen were unfurling the mystery of Maelstorm and the organization in the first half of 'The Flash' Season 6. The investigation will continue in the second half of the season.

Wallace confirmed that they wish to showcase Team Citizen is as important as Team Flash. “We wanted to give him a real investigation, which you're going to see coming up this season. As they kind of investigate Maelstrom, what they will discover is, I think, a whole larger world of thrills and almost a — I'll use the word a conspiracy. I think that's the best way to phrase it,” he said.
