Two of them, actually.

Living With Yourself

Netflix

exchanges with his doppelganger.

Confusions and complications ensue as old Miles lets new Miles excel for him at work and around the house.

The finale ends on Kates nervousis-this-actually-a-good-idea?laugh.

LIVING WITH YOURSELF

That whole episode was very complex, Rudd tells EW.

The mouth-to-mouth was another technically complex thing, shares Rudd.

Rudd approved of the bizarro bonding machination.

It seemed to be a sensible place to go, he says.

This story would inevitably lead to somewhere that would be another challenge.

So to come to this resolution was nice.

Especially for old Miles.

I think it might have been the only time he smiled in the whole show.

Miles may have been smiling, but Kates face told aslightlydifferent story.

Why would they stay together just over a weekend fling?

Of course,Living With Yourselfpresented this issue in the most of unusual scenarios.

Whats gonna happen?

It cant be the same movie again, she notes.

Do we have another clone of Kate to help out?

What if the babies were twins?

How do you co-parent?

How do you explain it to people?

Theres all the different things that bring up new trouble.

Old Miles seemed to move past Kates affair with new Miles in the excitement of the baby news.

Hes fully deserving or whatever he gets at that point.

Theres plenty of blame to go all around on every side here.

How would I feel?

I think its very confusing.

So I do think its not quite the same thing as a normal infidelity situation.

Bea points out that how one interfaces with this issue of cheating can fall across gendered lines.

Imagine if Kate had a clone and Miles went off and fed her clone, she tells EW.

I think all of us would not feel as kindly towards that situation as the gender reversal.

We would have all felt like, You fing dirty piece of s….

I dont think she should just totally get off the hook.

On this show, thats wild understatement.

So we did have to learn quite a lot.

We were like, Thats what we want.

So myself and Paul worked with her to make a unique-feeling dance.

And the pattycake bit is something Paul does with his daughter.

So there were little bits and pieces in there of our personalities, the characters, Pauls daughter.

So that felt like kind of kismet.

(It wound up causing a stir for a different reason;more on that over here.)

Working with him on set was really exciting, says Rudd.

As hard it is to say no to Paul Rudd, its impossible to say no to Paul Rudds.
