Justin Hartley Talks About Working With Sofia Pernas

Before Justin Hartley and Sofia Pernas worked together on Tracker, they met and worked together on another CBS series, Young And The Restless. Therefore, working together is not a new thing. However, as Justin indicated to TV Insider, he greatly enjoys working with her. However, he hints that in this episode, Colter may have asked “too much” of Billie.

Firstly, Justin shared that “something really big happens between them.” He continued to share that in this episode Colter “calls on a favor.” However, Billie didn’t recall owing him, resulting in Colter reminding her.

And then she comes in and delivers and she does exactly what he asked for. And by the end, he realizes that maybe he asked for too much.

Next, the This Is Us alum continued to share how in this episode, viewers learn more about what happened between Colter and Billie. He indicates that this is intense and cathartic.

And they have this really great moment that is just honest and pure and raw, and you find out a little bit more about their relationship and not necessarily what exactly happened, but that something big happened and that it was sort of unfortunate and now, are they going to rebuild?

He ends his Billie Matalon thought train with this, “There’s a lot of feelings there and a lot of emotion there. And you see it in this episode.”
