Rookie Blue's Missy Peregrym, who plays the beloved Andy on the hit ABC show, opened up about her and Sam's on-again-off-again relationship and revealed they have only reached the surface of their issues.

Love Triangle Between Sam, Andy & Nick Never Ending?

Peregrym told TV Line Thursday that the usually hesitant Sam revealing vital parts of his past serves as a turning point in their relationship; which is a good thing for fans of the couple.

She said, "It had come to this point where we needed to make a change. Otherwise, there was no point in getting back together. As nice as it is - 'Sam and Andy are together, and it's awesome!' - unless we're willing to be vulnerable with each other and open up, we can't actually move forward. So I was really excited to do this scene. I was happy that we were going there.

Still, this doesn't mark the end of the questions Andy has about Sam nor mean the relationship will be smooth sailing from hear on out.

Peregrym added, "There's always something to learn. I don't want to say too much, just because of things that come up later in the season that are pretty huge, that they need to work through...Sam really likes to have it all together and he doesn't like being exposed. Andy has a gift of being empathetic and vulnerable and all these things, but Sam protects himself from that."

She went on to say that Sam will be "pushed" even more to open up to Andy, and Andy will have to learn to live and cope with what she learns about Sam.

See how it all plays out when Rookie Blue airs Thursdays at 10/9c on ABC.
