'Marvel's Agent Carter' Spoilers: Will Hayley Atwell's Peggy Carter Discover Chad Michael Murray's "Dark Past?" [WATCH]

With the first season heading towards its fourth episode on ABC, new teasing info has been released about Marvel's Agent Carter. As the hunt for Howard Stark (Dominic Cooper) continues, will Peggy Carter (Hayley Atwell) discover Jack Thompson (Chad Michael Murray)'s "dark past?"

In our first recap, Peggy was seen as a hero as she fought bravely in World War II, but her co-workers at the Strategic Scientific Reserve think she's a complete joke. Framed for crimes he didn't commit, Howard Stark (Dominic Cooper) needs Peggy to clear his name after his inventions, which he calls "bad babies," have been stolen. The search for a glowing bomb leads to the death of Peggy's roommate and a warning from the Leviathan.

In our second recap, Peggy searched for the assassin who murdered her roommate. The killer and Peggy fought on top of a moving truck rigged to explode. Peggy got her revenge but the deadly confrontation might lead the SSR team closer to he,r after they discovered a certain clue from a previous wreckage.

In our third recap, Jarvis, Stark's butler, was being interrogated by Jack, until Peggy ruined the investigation on purpose. The two were at odds until their partner Ray (Kyle Bornheimer) was violently murdered. Whether they like Peggy or not, the SSR team has to pull together to find Ray's killer.

Will Peggy discover who Thompson really is as their manhunt continues? Murray tells Zap2it, "I think you have to look beneath the surface of who Jack Thompson really is. He's a driven man who has a dark past that the audience isn't necessarily privy to just yet. I think he has a rhyme and a reason for everything he's doing -- and you'll find out, especially when we get to the finale. You'll see a lot throughout the course of the season."

The One Tree Hill actor adds, "I've been the moral compass before, and it's nice because I'm not confined to a box that maybe Lucas was. I have the opportunity to really play things up and do what's unexpected."
