[Warning: The following contains spoilers for Tuesday's Season 3 premiere of The Flash. Read at your own risk!]
After traveling back in time to save his mom from being murdered by the Reverse Flash (Matt Letscher), Barry had a few days of bliss living in a parallel life where both his parents were still alive and Iris was falling in love with him. However, it didn't take long for the time travel to catch up with him and Barry began forgetting the events of his previous life and risked losing his ability to remember he was The Flash at all.
He freed Reverse Flash to help him back to his old timeline, finding everything to be the same as when he left it except for the fact that Joe and Iris no longer speak to each other.
"What's hard about that is that we've watched two seasons of the West family being such a tight-knit unit," Patton told TVGuide.com. "Nothing really penetrates that family bond, but because of 'Flashpoint' and Barry's return to the original timeline, things are different. Iris and her father don't have a great relationship. That's something that Barry is going to struggle with and obviously he'll want to fix it in whatever way he can."
Unfortunately, Barry's time-traveling excursion also erased his and Iris' conversation from last season about giving their romantic relationship another shot. That's something that will have to be addressed in the next episode when Barry finds Iris again.
"That conversation did not happen and she has forgotten about it, which makes it very exciting going forward. It'll be really interesting to see what she remembers and what she doesn't about that specific event," Patton confessed.
Yes, it's like Season 1 all over again, and when Barry and Iris were finally on track to being together and then time-travel rerouted their romantic destiny. However, Patton promises that there's a lot of Barry and Iris cuteness to come (just like the unbelievably adorable meet-cute they had in the premiere).
"There's a lot of cute romantic scenes with Barry and Iris [this season]. It's really fun to see. It's personally my favorite part of shooting the show. There's a lot of really great Barry/Iris interaction. If you like that aspect of our show you're going to be really, really pleased," Patton said.
So, while Barry and Iris might be far apart right now, fans should remain optimistic. It's written in the comic-book stars, after all.
"It plays to this idea of a one true love and a destiny, that's a very romantic idea. It's quite lovely that it doesn't matter where Barry goes, no matter what timeline or what Earth, it's this fixed point in the sky for him," Patton gushed. "She's always essentially Iris. The heart of her is always the same. She's always a good person. She's always going to find him."
Are you rooting for Barry and Iris this year? After two seasons, they've earned a piece of a happy ending.
The Flash airs Tuesdays at 8/9c on the CW.
