'Marvel's Agent Carter' Spoilers: Twitter Reacts To Hayley Atwell, Shea Whigham's Roger Dooley Shocker! [WATCH]

The countdown has begun as Marvel's Agent Carter has only 1 episode left on ABC. Before Howard Stark (Dominic Cooper)'s fate is decided, Twitter had lots to say as Peggy Carter (Hayley Atwell) and Chief Roger Dooley (Shea Whigham) had the biggest shocker of 'Snafu' as Leviathan attacked SSR headquarters.

In our first recap, Peggy (Atwell) 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.

In our recent recap, Ivanchenko had hypnotized Roger (Whigham) and strapped a bomb to his chest. Carter couldn't stop Roger as he grabbed a gun, ran across the room, and jumped to his death. While SSR headquarters felt the shockwave of the bomb explosion, Ivanchenko unleashed Starks' nerve gas, which killed every moviegoer in the theater.

In an interview with Entertainment Weekly, executive producer Michele Fazekas reveals why Dooley had to die, " It has been an idea almost from the beginning-almost from before we had cast the role. We knew we wanted something big to happen and something that had actual consequences that wasn't just a red shirt getting killed. It was very early on when we were breaking the season arc."
