Arrow's Katherine McNamara reveals whether she could return again as Mia after The Flash Armageddon crossover

Arrow star Katherine McNamara is set to make her long-awaited return to the Arrowverse in the final part of The Flash's huge crossover event.

Debuting tonight (December 14), Mia Queen will cross paths with Barry Allen on 'Armageddon' as she drops in from the future to save a "loved one"… whoever that may be.

However, could the cameo mark the first of more appearances for the character? Well, McNamara is certainly open to the idea.

"I would love nothing more than to come play in the Arrowverse again," she told Entertainment Weekly. "Truly, if anybody needs a gal to come shoot some arrows at some bad guys in a cool supersuit, just cast a green arrow in the sky and I'll come running.

"That was the biggest gift, I think, on this episode: that we didn't know whether Mia could come back or what happened or where the mythology stood on that, and Eric [Wallace] and the Flash writers were so wonderful to leave that door open and to make it possible for her to be a part of this world again.

"It's really an honour, and now maybe there's a potential for a future there."

Speaking previously about reprising her role, McNamara admitted it was a "dream come true" to come back to the franchise.

"They wondered if I was interested in coming back to play Mia for an episode of The Flash," she recalled to Collider of initial discussions. "I said, 'Absolutely! I will be there. You let me know. I'm yours.'"

The star added: "I learned so much from and had such an incredible experience on Arrow. They did so much for me and took such good care of her."

The Flash airs on The CW in the US. Sky Showcase and NOW air the show in the UK.
