Plus, what Kaley Cuoco and Chris Messina want to see from their characters in a potential follow-up.

Talk about a killer ending.

It’s a lot to take in and it leaves several interesting avenues open for a potential season 2.

Cuoco, Messina, and Bateman agree they’d love to do more.

“He’s really got this plan mapped out in his head,” Bateman tells EW.

“And I feel that with where it ends, season 1 is just so delicious.

He’s very, very funny.

He’s kind of trying to be sweet and tender and caring sometimes.

He can be a nice guy.

He’s all of these things mashed up into one person.

Cuoco and Messina say they wouldn’t mind playing a similar darkness in their characters.

“Turning totally dark that’s actually really cool.

Yeah, I like that.

Nice job,” Cuoco says with a laugh.

“I like where you’re going with that.

I like the idea of becoming more and more like Matt.

That would be interesting to me.”

There’s one thing that Cuoco doesnotwant to see happen for her character, though.

“I just hope I’m not pregnant again,” she says.

Ever quick with a joke at his costar’s expense, Messina quips on queue, “Me too.

It’s a real pain in the ass.

Let me tell you.

It was a lot on all of us, let me say.”

“There would be a baby.

There’s a lot of things that we did.”

Has it been going on longer than it appears?

Bateman says he doesn’t think so.

It’s Bateman’s hope that this angle gets explored more in potential future episodes.

So I’d like to see that a lot more."

And I think that sort of tug of war is quite fun.

I’d like to see that happen, personally."

But, that’s getting ahead of himself.
