ET on ABC Family.
ENTERTAINMENT WEEKLY: Could you talk a bit about the reunion between Lena and her mother?
Its been something thats eaten away at her for decades.
Its pretty intense, its a really intense episode.
It was written by Marissa Jo Cerar.
But its one that is more than relevant, but more relevant than ever now.
When you first read this topic would be in the script, what was your reaction?
My mom is white; the only family I ever knew theyre all white.
I was always the ethnic person in my class and in my town.
It felt ugly, and I felt shameful and awful.
Sometimes we curse our beloved creators and writers they do draw these storylines from their own experiences.
And I kinda do.
I knew intellectually like, yeah, I bet it would affect how I felt about things.
But its unbelievable the change I see in myself since having kids.
Everything is just more raw.
The situations these kids get into I feel it 100 times more now that I have kids.
How does the tension escalate between Lena and her mom?
How does it impact their relationship?
Her mom doesnt have her on her head, she doesnt just tell her to get over it.
I think she takes notice of her daughters feelings and validates them to a degree.
Its difficult because its one of those things thats so deeply personal and visceral.
I wouldnt advise her to hold it in because obviously its holding her back.
I definitely would advise her to speak her mind but just dont have expectations of how its received.
You cant change other people as much as youd like to.
you’re free to only speak your truth and move on if you have to.
Shifting gears a bit, how will A.J.
I think its the same every time we open our house open to a new child.
Theres an adjustment period, you know to say the least.
But, we dont give up easily just because a kid has issues or causes waves in the family.
Thats how deep our love goes for kids, kids who are lost and in need of a family.
Just the moment that Brandon comes into his own is a good way of saying it.
The pride we feel as a family for him is just overwhelming.
I really enjoyed that scene and I hope everyone else does too.
How do you think Lena and Stef would celebrate the news of marriage equality?
Will this be a point that we talk about on the show?
Im sure theyll drop it in somehow or another because it is whats happening.
Weve shown ourselves to be very relevant on our show and very topical.
We dont really have the money or the time for a getaway, obviously so no Catalina.
But we can celebrate in our kitchen with the Catalina-shaped hole in the ceiling.
