Showrunner Julie Plec has revealed what would have happened in Containment Season 2 had the CW series not been cancelled, per EW:
We had so many plans, and what’s exciting to me, in the midst of my despair, is that the Belgian company has made a second series of the show, so we get to see their story continue on. Maybe if nothing else, more people will watch that now that they don’t get to watch ours.
We really wanted to spend a season dealing with the day-to-day community building of being inside a quarantine that feels like it might never end and really explore what society goes through when they are essentially left to die. And then we were planning on building a really tremendous conspiracy outside the cordon that Leo Green was going to be chasing in a great kind of All the President’s Men way as he connected the origins of the virus back to a big pharma company. We wanted to see what it was like for Lex to end up in a community where suddenly Jake was really, for all intents and purposes, the mayor, and what conflict that would create between those two friends. We wanted to see Jana as the mama bear queen of the community as we see people starting to experiment with how do we communicate, can we have radio, how do we get the message out, how do we educate our kids? What’s poor Quinton going to be like as a teenager growing up in this community? What are the other kids? Are they troublemakers? We had a lot of plans. And I’m super sad that we’re not going to be able to tell those stories.
Speaking to TVLine, she added:
We had the conflict at the hospital. As the entire community is waiting for the virus to die out, knowing they won’t be free until it does, Dr. Cannerts comes up with a way to keep people alive, even though they’re symptomatic. So there’s a bunch of people, diseased and able to spread the virus, that he’s keeping alive and healthy but still infectious. Suddenly, these people who just 20 days ago were outraged to be placed in a cordon find themselves having to cordon off an area within their own zone so that they can potentially avoid infection from the people at the hospital. So we had a great cuckoo’s nest kind of division: the hospital filled with sick and dying people versus a community of people trying to build and hold on and survive in functional ways by deciding what to do about communication and law and martial law and how to feed themselves and how to teach their kids and how to be intimate with each other — all the things that you need to have when you’re stuck somewhere and you’re not going anywhere anytime soon.
