On Thursday's night's episode of "Rookie Blue," fatherhood was the focus of the episode, which hit home for Sam (Ben Bass) as he soon approaches fatherhood with his ex Marlo (Rachael Ancheril) and not his current love, Andy (Missy Peregrym).

The episode takes a dark turn as David Sutcliffe ("Gilmore Girls") plays "an abusive, overly controlling, super-strict father" to "Orphan Black's" Zoé De Grand Maison, aka Gracie, TV Line reports.

Controlling and obsessive about the clothes she wears, Sutcliffe delves into the dark side and, like a villain, he makes his daughter sleep in a freezer in the garage when she disobeys him. His wife is too afraid to stick up to him or leave him, but then she realizes how toxic he is and how his credulity is truly affecting her children.

Following in the footsteps of his cruel father, the little brother attempts to poison his sister for her rebellious behavior and that is when the mother has to draw the line.

In a sense, the storyline that highlights the role of a father -- in that case a poor example of one -- parallels the ordeal between Andy and Sam. The couple is trying to figure out their feelings over the fact that Sam's ex, Marlo, is going to have his baby.

Using the horrible situation with the abusive father (played by Sutcliffe), Sam realizes how some people approach fatherhood in a completely wrong way.

With that said, Sam recognizes that he has the chance to make it right and be a good father and a good example and not "screw up his kid." At the same time, the idea of being a parent can be frightening, knowing the effect a father can have on his child.

"For the first time in my life, I think I could be a good father," he told Oliver. "I know I'm not going to be like my dad. That's because of McNally (Andy). I couldn't wait to do this with her. How am I supposed to do this with Marlo?"

"The best thing you can do for your kid is just to be happy yourself," Oliver said.

Andy doesn't know how she's going to fit into this new dynamic and admits that she too is "terrified." So should she just step away?

After witnessing the disturbing case, she comes to realize that some families may not be conventional, but that if there's love and understanding present, then things can work out in the end.

In an emotional moment, Andy put her acting skills to the test, saying, "Did I want to be the woman to make you a father? Yes. But just because this isn't what I pictured, doesn't mean I fold, OK? I have no idea how to do this. And I know it's not going to be easy."

Andy continued, "But what I can say is that I love you. And I will show up, and we're going to figure this out. I promise you, there's not going to be a day where that child does not feel wanted or loved by me."
