Warning: Contains SPOILERS for Succession season 4, episode 5!

Shiv and Lukas Matsson definitely have something going on in Succession season 4, episode 5, and here's the big love triangle setup explained. Shiv's love life has always been a major part of Succession, with her marriage to Tom being key to her character arc. However, Shiv seems to be moving away from Tom and to Lukas Matsson, with this potential relationship having the potential to change the course of Succession season 4 completely.

Succession season 4 is the final season of HBO's beloved comedy-drama, with the series finally wrapping up the story of the Roy family and Waystar Royco. Although Succession season 4 is only halfway done, it has already dropped all kinds of major reveals, with one of the most notable ones being the death of Logan Roy. This event has significantly shaken up the Roy family, but Shiv has somehow managed to keep moving on. Now, Shiv has been talking to Lukas Matsson, and it seems like their relationship is much more than just business.

Are Shiv & Matsson In A Relationship In Succession Season 4?

Although this storyline is just being set up, it seems as if Shiv Roy and GoJo CEO Lukas Matsson are starting a relationship in Succession season 4. While in Sweden with the rest of the Waystar Royco employees, Shiv and Matsson get some private time, with the two discussing personal issues. Matsson asks for some advice from Shiv, while Shiv seems to genuinely open up to him. While the two didn't get physical, sparks were flying, hinting they may be entering a romantic relationship.

Despite the signals, Shiv's desire to enter a relationship with Matsson has more to do with her vendetta against Tom. In Succession season 4, episode 5, Shiv tells Tom about how much more attractive Matsson is, clearly trying to make her estranged husband jealous. It isn't clear if Shiv actually has feelings for Matsson or if he's just a pawn, but either way, something is going on between the two of them.

How Shiv's Love Triangle Changes Succession Season 4

Shiv's love triangle with Tom and Matsson will seriously change the rest of Succession season 4. For starters, it could influence GoJo's acquisition of Waystar Royco. It's no coincidence that Shiv talked Karolina up to Matsson only for her not to be on the kill list later in the episode. Matsson's favoritism of Shiv could have an influence on Waystar's business dealings going forward, fundamentally shifting the GoJo storyline.

Another way in which the love triangle will change Succession season 4 has to do with Shiv Roy's pregnancy. It's been heavily implied that Shiv Roy is pregnant in Succession season 4, and this could throw a wrench into the love triangle. Despite her difficulties with Tom, Tom will most likely want to be with Shiv if she is pregnant. This may cause his jealousy of Matsson to grow, making things worse for everyone. As a result, Matsson will probably play a big part in the rest of Succession season 4, with Shiv's relationship with the CEO being further expanded on.
