"Eddie's death will have a major impact on all of their lives as they cope and figure out how to move forward in season two."
Kreisberg added of Eddie's exit: "Having someone do the ultimate sacrifice ups the life-and-death stakes.
"At the end of the day, [Eddie] dies knowing he is a hero. He eliminates Eobard from existence."
The showrunner also confirmed that Tom Cavanagh, who plays the Reverse-Flash / Dr Harrison Wells, will be a part of the second season, but refused to share details.
The Flash airs on The CW in the US and Sky1 in the UK.
