'Shadowhunters' season 3 episode 20 spoilers tease an epic showdown between siblings Clary and Jonathan vs. the Lightwoods

This article contains spoilers for season 3, episode 19 'Aku Cinta Kamu'.

It's a big week for 'Shadowhunters' fans and this is not the time to keep calm. Over the last nine weeks, we have seen the third and final season get darker with each episode and as our protagonist, Clary Fray (Katherine McNamara) gives into the dark side, the upcoming episode 20 titled 'City of Glass' promises both action and tension in equal parts. 

The trailer for the upcoming episode is a major reminder that initially, this very episode was supposed to be the series finale before Freeform decided to go ahead and plan an additional two-hour-long finale to give fans the closure they need. But while some major loose ends get tied, the episode also opens up a whole other set of sub-plots, something that will leave fans on the edge of their seats anticipating the big finale.



The trailer starts off with the impending fight between the Morgenstern siblings and the Lightwood siblings. Meaning, Clary and her evil brother, Jonathan Morgenstern (Luke Baines) will be fighting against Jace Herondale (Dominic Sherwood) and Izzy Lightwood (Emeraude Toubia.) The fight happens after Clary and Jonathan manage to abduct the Seelie Queen and acquire the Morningstar Sword, but team lightwood, on the other hand, has been able to forge the Glorious sword which has the Heavenly Fire serum, capable of severing Clary and Jonathan's bond from the life-force rune.

The biggest tease in the trailer, however, arrives in the form of what looks like a kiss between Jonathan and Clary, which even though sounds wrong and creepy, has to come with some explanation. We already know that the two share the same father and were born of different mothers. They were together when they were little kids but were soon separated and then grew up without any contact with each other, until this season of the show. Either way, it is still pretty weird because so far we have seen Jonathan treat Clary like a little sister, but then again, he does get pretty jealous whenever Jace - aka Clary's boyfriend - is third wheeling with them so maybe this kiss is him finally acting on that latent rivalry Or whatever evil plan is brewing in his brain currently. 





In other news, we see a heartbroken Magnus Bane (Harry Shum Jr.) indulging in his father, Asmodeus' plans of controlling the entire demonic realm together. But the reason behind Magnus' heartbreak, his ex - Alec Lightwood (Matthew Daddario) - will be seen executing his duties as the head of the shadowhunters' Institute without even bothering to find out whether Magnus has regained his powers or not. 

Speaking of exes, Maia Roberts (Alisha Wainwright) and Jordan Kyle (Chai Hansen) - who have rekindled their romance - are fronted with the dilemma of choosing a mundane life over the werewolf life. As Jordan asks Maia to consume the Heavenly Fire serum to turn them into mundanes, she struggles to make a decision between love and her responsibilities as the newly appointed alpha of her werewolf pack. Luckily, the former alpha, Luke Garroway (Isaiah Mustafa) will arrive just in time to offer his signature fatherly advice that will probably help Maia see things more clearly. Sadly, that can't be said for Clary, who is still pretty much reeling under the impact of the life-force rune, so let's hope in episode 20 her friends are finally able to retrieve her before something worse happens.


'Shadowhunters' returns with season 3, episode 20 'City of Glass' on Monday, April 29, at 8/7c, only on Freeform.
