In the upcoming episode titled "There is a Crack in Everything" of The CW's miniseries "Containment" Season 1, it seems that after working rigorously for days to find the cause of the outbreak, Jake and Katie finally find about the truth of Patient Zero.

The synopsis of the episode, as stated by Spoilers Daily, reads:

"Dr Cannerts makes a major breakthrough that brings him one step closer to finding a cure for the virus. Meanwhile, after monitoring hospital surveillance from the day of the outbreak, Katie and Jake unravel the truth behind Patient Zero. Elsewhere, Jana and Suzy move forward with a plan to escape the cordon using the city's underground tunnel system. Finally, a risky operation to extract the potential antidote from the cordon takes an unexpected turn."

In the previous episode titled "Inferno," Jake and Katie found a boy named Thomas who was apparently immune to the deadly virus. The doctor started a research to find out whether Thomas' immunity can help to create a cure for the plague or not.

The synopsis of "Inferno" reads:

"DON'T GET CAUGHT — With the cordon now under the purview of the National Guard, Lex (David Gyasi) finds himself clashing with Captain Lee Scott (guest star Miles Doleac), who is now in charge of the operation. Inside the cordon, Jana (Christina Moses) steps up after the data recovery centre comes under attack by a violent group of addicts looking for more drugs.

Elsewhere, Xander (guest star Demetrius Bridges) and Leanne (guest star Tiffany Morgan) continue to disagree over Teresa (Hanna Mangan Lawrence) and the baby's best interests, while a desperate plea from Jana leaves Lex's world turned upside down. Chris Wood also stars."

"There is a Crack in Everything" will showcase the errands of Dr Cannerts as he will try his best to find a cure, while Jana and Suzie will be seen working on a way to escape the cordon.
