As the season wraps up, Helens plan starts to bear its fruit but nobody seems to know what fruit that is. Magnus has kept everything hidden from all of those around her and nobody is sure what she is planning. As a first step she has wallstreet shut down for 15 min, for reasons unknown. As she moves forward, she ends up getting an invitation to meet Caleb, a former Hollow Earth insurrectionists. He has a plan for a new sanctuary for abnormals and one that serves as a step to move abnormals into surface life among humans. Helen takes to this plan, but Will is a bit more hesitant.
Will doesn’t get much of a chance to object before Addison forcibly calls Will into work for SCIU. Will is threatened with defamation and more if he doesn’t go, and Helen doesn’t put up much of a fight. It all feels a bit planned out. Despite Wills objections to Helens secrets and lack of trust, he still defends her when working at SCIU. Addison doesn’t have to wait long to try and change Wills loyalty when he shows him a video feed of Helen and Caleb braking out imprisoned Hollow Earth insurgents from a detention facility. All of this calls Wills loyalty to Helen into question. Addison orders him to arrest Helen, which he attempts but fails to complete after a few punches are pulled.
Addison makes the call and SCIU descends on the fifth ward where the new sanctuary was setting up and contains all of the abnormals in a prison and tells the public its a toxic waste spill. It would seem that both Helen and Addison had plans in place for the abnormals. With all of the abnormals surrounded and seemingly eager public to accept the toxic waste story, Helen goes out to the news camera and makes the admission of abnormals and monsters. The question now is, where does it go from here?
After Helens stunt with the news, she has bought a little time for Henry and Nikola to figure out what is being used to keep the people stuck in the fifth ward. In the mean time, Will is starting no longer doubt his loyalty to Helen but try to figure out what exactly she has been doing. Addision is getting pressure above and finds out he doesnt have the control he thought he did and someone else is calling the shots above him. In an effort to get some answers he asks Will for some straight answers, which Will both doesnt have and wont give.
Will asks for 1 thing from Addison to try and help, access to the secure networks that the sanctuary was locked out of. Henry and Nikola figure out what is keeping everyone from leaving and its an invention Nikola created. This force field however can be manipulated to create an electronic storm that would instantly kill everyone in the fifth ward, an alteration that Nikola never intended and is very upset over. Helen tries to convince Caleb that they must leave, and she tells Caleb what they are planning to do with the devices. He refuses and wants to stand his ground. Helen thinks he is hiding something.
Biggie finds out what Caleb is hiding would ‘change the world forever’. Biggie finds a way to sneak the item out and get it to Nikola for testing. Biggie is beaten when Caleb finds the stuff missing. With some testing Nikola discovers its a praxian virus that when unleashed would force the dormant abnormal genes in all humans to manifest, resulting in the extinction of the human race. With Henrys help, they figure out a way to disable the power and get the people out of the fifth ward. Will talks with Addison asking for a stall on the final solution to get those people out. Addison plays ball knowing he doesnt have a say anymore and doesnt want to be a part of a mass genocide.
Will and Abby with access to the worlds databases again, trace down Helen over the past 100 years she was supposed to be in hiding under her mothers madden name. They discover that she was very busy and they discover the reason wallstreet was shut down for 15 min. Helen liquidated everything during that time so nobody would see what she was doing. The question is, where is all that money going? From Will and Abbys research at least 4 of the world sanctuary’s were abandoned.
Just as Helen, Henry and Nikola shut down the power, someone is at the front door. Biggie is on the ground, lifeless and just in front was Caleb along with 4 others waiting for Helen. She pumps a few rounds into Caleb and runs inside. Will gets everyone out and heads back to the Sanctuary, just as Addison radios that they are just about out of time. In the sanctuary Helen lures Caleb and the others into the lab, she tells Nikola to leave just before giving him a kiss and he shuts the lab off. Henry and Nikola make a run for it sealing off the final door as Helen battles Caleb. She gets on the computer and starts a file purge and a count down. As Caleb sees it and tells her to shut it off, she impaled him and we see the entire sanctuary blow up and burn to the ground. Henry and Nikola made it out, we have no word on biggie, Will, Kate and the abnormal look on in horror from the near by street as they see it blow up.
Addison, seemingly knowing what was going to happen, says “Hell of an exist”. The real question is did Helen survive? She did. Will follows a signal underground and finds a locked door with a retina scanner on it. He is scanned and allowed in and Helen is there to meet him and when she finally shows him what she had been doing, he is in awe. Helen has rebuilt a part of Praxsis and a new place for the Sanctuary to continue.
What happen to the others and what is in store for the sanctuary. Hopefully SyFy will decide to continue the series and we will find out. Sound off on your thoughts about the entire season and what you want to see from Sanctuary if season 5 is a go.
