She knows
In “Kristin,” a second-season “Knots Landing” episode, Kristin and Valene (Mary Crosby, Joan Van Ark) argue in the Ewings’ guest bedroom.
VAL: If you’ve got something to say, Kristin, I think you better say it.
KRISTIN: [Looks away, begins tearing up] I’m pregnant. [Sits in a chair]
VAL: Pregnant? [Sits on the edge of the bed]
KRISTIN: I didn’t wanna tell anybody. I thought it would be easier for the baby if I kept it a secret. I hoped to find somebody who would be a father to my baby.
VAL: Do you know who the father is?
Kristin is silent. Val moves off the bed and kneels in front of the chair.
VAL: Do you love him?
KRISTIN: I don’t know.
VAL: Darling, why didn’t you tell me this before?
KRISTIN: I was afraid that if I told you, you wouldn’t help me.
VAL: Oh, no, that is not true.
KRISTIN: You wouldn’t have let me in.
VAL: Oh, no, Kristin. You’re wrong. I would have. I know exactly how you feel right now.
KRISTIN: No you don’t. Nobody does.
Val lays her head in Kristin’s lap.
Dallas Decoder 
I liked this side of Kristen that we did not see on Dallas. You could feel for her. Shame the show did not keep her on. When she went back to Dallas, it was if this did not happen.
