Everything will be different when The Flash returns for season three in October—but as far as Barry Allen is concerned, life is beautiful.

"He's over the moon at the moment because his dream came true. He's living with his parents and he gets to see them every day," executive producer Aaron Helbing tells E! News of our hero's mindset in the season opener, "Flashpoint."

But by going back in time in the season two finale, Barry (Grant Gustin) has completely reset the timeline—which means that his actions affected everyone, not just himself. We spoke with EP team Aaron and Todd Helbing about what other changes we'll notice as the Flashpoint storyline plays out.

Warns Todd, "There's consequences to every decision you make, and with Barry, it's a lesson that he keeps learning over and over, especially when it comes to time travel—the consequences are sometimes a lot more severe than you expect."
