It’s DC crossover week! ‘Crisis on Earth X’ begins tonight with Supergirl followed by a special episode of Arrow.  And continues on Tuesday night with The Flash and concludes with DC‘s Legends of Tomorrow


So what is it that you need to know about these shows before Monday night’s premiere?  If you haven’t been watching, be prepared…there are a few spoilers ahead. 



Barry  met Kara’s (Melissa Benoist) boyfriend Mon-El (Chris Wood) during the musical crossover.  Kara, a Kryptonian, and Mon-El, the Prince of Daxam have similar powers, but were meant to be enemies. Which is why Mon-El’s mother disapproved of Kara.  Rhea (Terri Hatcher) interfered with their relationship, attacked National City, and tried to force Mon-El to marry Lena Luthor (Katie McGrath).  Rhea also infected Superman (Tyler Hoechlin) with Silver Kryptonite to make him fight Kara.  The only solution that Kara could come up with to get rid of Rhea and Daxomite army was to release lead into the atmosphere. The lead was extremely toxic to the Daxomites and they were forced to leave Earth, including Mon-El.

Kara hasn’t been the same since. She focused all of her attention on work so she wouldn’t think about Mon-El.  It took Alex, Lena, and new friend Samantha (Odette Annable) to get Kara to start living again.  (BTW, Samantha was revealed to be a Kryptonian…and she’s evil.)

Alex Danvers (Chyler Leigh) was dealing with some emotional issues herself after meeting and falling in love with Maggie Sawyer (Floriana Lima).  They were set to marry but things changed when Maggie told Alex that she did not want kids.  Alex had always dreamed about being a Mom, so that was a deal breaker.  Alex and Kara recently took a trip home to recuperate from their broken hearts.

And guess who shows up…Mon-El, but he’s different.  When Mon-El left earth, he traveled through a wormhole.  He lived in the 31st century for seven years before being able to return to the present Earth.  He didn’t come alone.  There are others on the ship he travelled in…including his wife.  Poor Kara.

Last season, Oliver Queen (Stephen Amell) was voted in as the mayor of Star City. This was a conflict of interest for him being the Green Arrow and all.  He recruited a team of vigilantes, who saw a little action in the last Crossover. Wild Dog Rene Ramirez (Rick Gonzalez) and Mr. Terrific Curtis Holt (Echo Kellum) are still on the team that has a new Black Canary Dinah Drake (Juliana Harkavy).

Another new face is William Clayton (Jack Moore), Oliver’s son and the reason Oliver hung up his hood.  Season 5 ended when Adrian Chase/Prometheus (Josh Seggara) kidnapped William.  Oliver, all of Team Arrow, and William’s mother went to a deserted island to rescue him.  Oliver also enlisted the help of Slade Wilson/Deathstroke (Manu Bennett) to help him save William.  The season ended with Oliver and William watching Adrian kill himself so that the island would blow up.    

William’s mother was the only casualty from the island explosion. Thea Queen (Willa Holland) was hurt and in a coma.  She woke up at the end of the last episode. William thinks the Green Arrow is bad. And the FBI is hot on Oliver’s trail.  So to put William’s mind at ease and to throw off the FBI, Oliver asked John Diggle (David Ramsey) to be the Green Arrow.  Great idea! But John was hurt in the explosion as well.  He has nerve damage to his arm.  He hid his injury from everyone but Dinah.  John started taking steroids to help his condition, but it made things worse. Now the nerve damage has spread to his back. He has to heal before he can continue as the Green Arrow

That would be okay if Cayden James (Michael Emerson) and the Black Siren Laurel Lance (Katie Cassidy) weren’t reeking havoc around Star City.  James is out for revenge on the Green Arrow for the death of his sister.  Although, it is not clear how James intends on getting his revenge yet.  All the team knows is that James is after certain technologies and Black Siren is helping him to get it.  At the same time, they are exposing the team as vigilantes. Star City just passed an anti-vigilante law.  This is bad news for Team Arrow.

DC’s Legends of Tomorrow

The Legends really messed up this time. It’s so bad that Rip Hunter (Arthur Darvill) started a new organization, The Time Bureau to fix all of the Legend’s anachronisms.   But  the Legends are not the only thing that Rip is chasing. He has been seeing signs of someone called Mallus.  A dark force with followers that include Damian Darkh (Neal McDonough), his daughter Elenor (Courtney Ford), Kuasa (Tracy Ifeachor), and Gorilla Grodd.  The Legends team also got a new member, Zari Tomaz (Tala Ashe), a “hackivist” from the future with a totem similar to Amaya’s (Maisie Richardson-Sellers).  The two are connected somehow.  What’s more interesting is that Amaya is also connected to Kuasa…her granddaughter.  

Professor Martin Stein (Victor Garber) has had a life changing event.  His daughter, Lily (Christina Brucato) had a baby at the beginning of the season.  Jefferson “Jax” Jackson (Franz Drameh) feels how much Stein misses his family and enlisted the help of Ray Palmer (Brandon Routh) to find a way to find a way to split up Firestorm. He wants Stein to have a normal life as a new grandfather.  Stein gets an opportunity to speak to Sir Isaac Newton about the split and learns that the split would cause Jax to lose his power. 

The Flash,

The Flash

Geek Girl Authority has been covering The Flash all season long.  Barry (Grant Gustin) and Iris (Candice Patton) are getting married and the Arrowverse will be in attendance for the big event.

At the end of season three, Barry went to the speed force.  In season four, Team Flash brought him back.    It took some adjusting, but Barry was back to his oldself…but better.  He soon found out that his return created twelve metahumans in the process. The dark matter from the speed force hit a bus with pedestrians.  Team Flash has been searching for the new metas and came across the name DeVoe.  According to Savitar and Abra Kadabra, DeVoe is Barry’s greatest nemesis. 

Barry found Clifford DeVoe (Neil Sandilands). He seemed pretty normal at first, but Clifford is super smart.  He knows what Barry is going to do before Barry knows.  The rivalry is being put on hold for Barry’s wedding. Clifford knows what it’s like to be loved. He says there is no knowledge without love. 

During all of this, Iris continued her wedding plans.  Wally West (Keiynan Lonsdale) left to find his own journey and returned for the wedding.  Caitlin left when Killer Frost fully emerged and came back when she had a handle on her alter ego.  Harry Wells returned from Earth 2, mainly because Jessie kicked him off her team.  And Joe’s (Jesse L. Martin) girlfriend is expecting.

Will any of this affect the Crossover? Maybe not, but it’s fun to look at the shows that make up this major CW event.  Just as reminder, here’s how some of these characters connect to one another.

Ray Palmer used to date Felicity Smoak (Emily Bett Rickards), who broke up with him to date Oliver Queen.  Felicity also owned Ray’s company for a short time.

Professor Stein used to work in Central City. His first Firestorm counterpart was Ronnie Raymond (Ronnie Amell), Caitlin Snow’s (Danielle Panabaker) husband. Ronnie died helping The Flash save the world.  Barry helped Stein find Jax to keep Stein’s power from killing him.  

Sara Lance (Caity Lotz) is the sister of Laurel Lance and both sisters were involved with Oliver Queen.  Laurel died, but her doppelganger has emerged from another Earth.  She is known as the Black Siren.

Harrison Wells (Tom Cavanagh) also has several doppelgängers throughout the other earths. Just a reminder that the first Harrison Wells was actually Eobard Thawne, the Reverse Flash.

Mick Rory (Dominic Purcell) started as a villian on The Flash. His partner was Leonard Snart (Wentworth Miller), Captain Cold. The two joined the Legends to get rich.  Snart sacrificed himself in season one to save the Legends. He also had  thing for Sara.  Snart returned in season three, but as a member of the Legion of Doom with Damian Darkh and Eobard Thawne (Matt Letscher).

Barry Allen and Kara Danvers became friends when The Flash accidentally crossed into Supergirl’s dimension. He helped her with a problem in National City before returning home. The two also shared a dream in the musical crossover last season. 

Felicity Smoak and Cisco Ramon (Carlos Valdes) often cross-collaborate to solve Arrow and Flash’s tech problems.  

There you have it.  A quick summary of how these people are connected and what they’ve been up to in their little worlds.  The CW Crossover Event, Crisis on Earth-X begins tonight on the CW.   Stick with Geek Girl Authority for recaps and Arrowverse news.
