A couple of slight spoilers land online out of Vancouver in the form of The Flash Season 3 set images.
The pics reveal Barry Allen smooching with the long time love of his life, Iris West.
Recall that the Season 2 finale saw Barry and Iris almost get together, but then Barry went back in time to save his mother, which will be the cause of all the timeline changes affecting Season 3 with Flashpoint.
It obviously appears one of those changes may be that Barry and Iris get together, which is what also happened in the alternate Earth-2 universe as the two were married.
Regarding why Barry didn't get together with Iris at the end of Season 2, Grant Gustin recently revealed that the reason Barry traveled back in time was because he felt empty inside, especially when he heard those words from Iris.
It's thought the additional changes with Flashpoint bringing Barry's family back will mean Barry is the most happiest he's ever been -- in any universe. Barry might not even be The Flash as Wally West is confirmed as playing Kid Flash.
The bad guy of The Flash Season 3 is also unknown, but Gustin did previously tease it's not a metahuman. Some sort of Black Flash has been spotted on set, but it's unknown how the Speedster will play into things or even if he's the "Death" Flash from the comics.
"The Flash" Season 3 returns on The CW Tuesday, October 4th at 8pm ET.
