"Quantico" Season 1 episode 12 will see one character being killed off.
In an interview with TV Guide, executive producer Joshua Safran said that more details about the second bombing at a nearby bank will be unveiled when the show returns this year.
"People we care about are in jeopardy and they don't all survive. The good thing about a show with dual timelines is you can still continue working with those character should they die, like even Elias could come back to us at Quantico even though he's dead in the future," he said.
Meanwhile, Safran also confirmed that fans will learn more about Shelby's backstory, according to Design & Trend.
During the first half of Season 1, Caleb learned that Shelby was just being conned by her alleged half-sister. However, Safran said that it's impossible for someone like Shelby to not know what's really going on.
"The next character's backstory is Shelby's. In fact, that was a piece that fell out of this episode. We decided the very last second we will hold it. We're interested in telling that story. It might be a very long con, but you can't con somebody that long," he said.
In other news, Safran also talked about the ending of the first season. According to him, he and his team are all aware as to how the season will end this year.
"The one thing I can say I'm very excited about in episode 12, which is our midseason premiere, is that it has as big as a story generator in it as the pilot in terms of a bomb going off in the beginning of the pilot. It gave the drive for this 11-episode stretch. Episode 12 also has a strong engine that neither of us, of course, will reveal now, but it will tell you the entire nature of the back half," he said.
"Quantico" Season 1 episode 12 will return to ABC in March 2016.
