On Quantico Season 2 Episode 11, we get an inside look at what is going on with the terrorist situation. Will is an avid believer in rooting out the members of the AIC, even though it means killing them.
Ryan, on the other hand, is not a fan of killing his friends, whether they are AIC or not. This causes tension between the terrorists, and it leads to a shootout. One terrorist dead, courtesy of Will.
Luckily for them, Alex shows up and tells them about the impending strike. Will tries to deceive the terrorists and buy them time to get the hostages out, but somehow, the terrorists find out. The plan to get everyone out is still in play, even if it means freeing the terrorists.
At the Farm, the lesson of the week is exfiltrating an asset who has been burned. The team practices at the Farm, thinking that they are going to be helping a man named Marcus Webber. Once they get to Germany, Owen reveals that they are actually there to make sure he gets home safely.
Owen has a death wish, and things aren't easy, but Alex (and assumedly everyone else) manages to get Owen back to the US safely. You see, before the trip, Alex filled Owen in on her theory that Lydia is behind the AIC, and it caused Owen to go off the rails. Back in the US, Owen finally agrees to help Alex catch Lydia.
While in Germany, the AIC gives Dayana, Leon, and Ryan another mission. Before Dayana can kill the target, Leon intervenes. As far as undercover agents go, Leon is not all that great. Leon can kiss that immunity deal with the FBI goodbye because after the Germany mission, Dayana tells Lydia that Leon is not loyal to the cause.
