Episode 13 of The CW's Walker, which airs June 10, was originally intended to be the Season 1 finale before five more episodes were ordered.

"Yeah, it was. And it didn't change when they added episodes, so it's an enormous, enormous episode," Walker star Jared Padalecki told EW. "It's the biggest by far. It was meant to be a three-part finale with [episode] 13 obviously being the big guns, so it's huge."

"I remember telling [his wife] Gen before we were shooting it, 'I'm going to be a little off for the next week and a half. I'm not really going to be present as a husband or father, I apologize, but there's so much,'" he continued. "I had to stay in a certain headspace. I really wanted to do it properly; I wanted to give everything to Walker. It's a huge episode. It was an enormous season finale, and now it happens to not be our season finale, but it's still equally as enormous."

In May, The CW confirmed Walker Season 1 will now conclude on Aug. 12.

Walker stars Jared Padalecki, Lindsey Morgan, Keegan Allen, Mitch Pileggi, Molly Hagan and Coby Bell. New episodes air Thursdays at 8 p.m. ET/PT on The CW.
