Sofia Pernas returns to Tracker as Bille Matalon. Billie first appeared in Season 1 as Colter Shaw’s rival when the pair worked on a related case together. Despite being at odds for most of the episode, they ended things amicably as they each moved on to other cases. In Tracker Season 2, Episode 3, “Bloodlines,” the duo reunited below when Billie sought Colter’s help in solving a case in the official storyline. The episode’s promo previews the missing person and the subsequent efforts to find him.
“Billie, so what’s this all about?” Colter asks Billie as the promo video above begins. “Missing high school baseball player disappeared two days ago,” Billie says, as the promo shows the circumstances behind the disappearance. Wolf Pack’s Tyler Lawerence Gray plays the baseball star who disappears during practice. The duo begin their investigation, which takes them to dangerous places and puts them in dangerous situations. “I’m going to do everything I can,” Colter tells the player’s parents.
The highlight of the episode is that Justin Hartley’s wife, Pernas, gets to share the screen with her husband again. It’s revealed that they had a past, which partly explains the instant chemistry between the actors. “I love the story of them having a past and she may have cheated on him a little bit. That’s how he feels, anyway. They haven’t worked it out, and he’s forced into this awkward situation of being with someone he probably doesn’t want to be with right now, not because he doesn’t like her, but because it’s painful,” Hartley told Collider’s Christina Radish. Hartley elaborated on why Colter acts the way he does around her by revealing a bit about his nature, saying, “Colter has emotions. He’s just a really vulnerable person. We had a great story, she’s a great actress, and we had a little fun with it. There’s pain there, there’s history there, and it’s a proud thing, trying to make sure she doesn’t know how hurt he is. It’s a really great story about an old relationship, and I’m glad people like it. I hope people like it. It’s a very different character than she is in real life. And I’m not being complimentary.
