WhenYoungercreator Darren Star promisedmore OMG moments in season 2, boy, he wasnt kidding!
On the revelation that Thad has a twin brother named Chad …
SUTTON FOSTER:Its great for us.
We love Dan [Amboyer] so much, so when Thad died we were like, Ahhhhh!

And they were like, Were just going to introduce him as if everyone knows except for you.
Were not going to make a big deal out of it.
It cracked us up.
Its actually such a funny sort of weird-ass twist to the whole thing.
On whether Liza needs to worry about Chad figuring our her secret …
FOSTER:I dont know!
I have no idea.
I hope that there is a world where the show has sort of grown beyond her secret.
In many ways its really become about these multi-generational relationships and sort of how people connect despite age.
I hope theres a time where the show can exist without this big secret looming.
When youre grieving you make some weird decisions sometimes.
So that could be a funny thing to explore.
Im sure theyre going to bring someone new in for Kelsey to have a romantic relationship with.
And I think that Chad is going to be more of a problem for Liza.
Thats whats so great about this show: Theyve presented two totally viable, fabulous options.
They both have things to offer, and they both have pluses and minuses.
Im curious to see how it plays out.
DUFF:Its really tough for me because I love them both so much as people.
I hope thats in the cards …
The only thing I would hope for in this next season is that she tells Kelsey.
Kelsey is sometimes a bit unpredictable, but I think shell be totally crushed and angry.
Because shes a very loyal person.
