SPOILER ALERT: Read on only if you have already watched Sundays Omega episode ofThe Walking Dead.
When someone started panicking, she killed him.
She then told young Lydia to put on a zombie skin mask and the rest is history.

Maybe something that was laying dormant inside of her.
And most women out there, and men, would say that they would do anything for their child.
Youd stand in front of a bus to protect your child.

But it is about protecting her child and herself, and surviving, and watching people behave so stupidly.
Youre pathetic and there is no room for you here, and smothers him.
Is she even phased by that?
But I think Ive imagined that shes killed animals before.
She grew up in a rural area.
Shes badass in that way.
Shes just doing what she has to do, and shes been really honest about it.
Its awful, actually.
When I think of it, Oh, my gosh!
Did you have to adjust to that at all?Yeah, we did.
Its a dream within a dream within a flashback within a what is real?
Because we all have that anyway.
So I find all that fascinating.
So, lets talk about the hair.
We see your hair at various lengths throughout the episode.
But I didnt realize we were going to go back, and that you saw the long hair.
Just go for it.
What was that like?Oh, I loved it.
It just feels very real, and what the audience is seeing is real, you know?
Shes metamorphosing from a caterpillar to a butterfly, but not the nicest butterfly, you know?
What can you say about that look that you all created?
Its pretty striking.I think those guys are incredible, what they come up with.
Thats what the [makeup artists] want, and I love it.
I think its brilliant.
The eyes are there because when she puts on the mask, they need to be hollow.
So, yeah, I just think its brilliant.
I think people do find her scary, so thats a good thing, I think.
So Im chuffed with that because I can just be the character then.
I dont have to kind of behave like some villain.
I think you just be, dont you?
And then I think all that makeup really helps.
Its a bit mad.
