Dina Learns That She's Pregnant In The Last Of Us Season 2, Episode 4

Due To Her Finding Pregnancy Tests

In The Last of Us season 2, episode 4, Dina makes the shocking reveal that she is pregnant. Early in the episode, Ellie and Dina are raiding an abandoned building for medical supplies. Not much is found, but one strange moment occurs at the end of the scene. Dina seems to find something that is helpful to her, although this mysterious item is off-screen. She lies to Ellie about what she is doing, with her grabbing this mysterious item. What Dina is actually doing isn't revealed until much later, with the audience learning that this mysterious item was a pregnancy test.

During the chase out of the subway station, Ellie sticks her arm in front of an Infected, getting bit in order to save Dina. The duo escapes, but Dina is horrified, believing that she will have to kill Ellie. Ellie reveals that she is immune, with her telling Dina to wait one night and see. The next morning, Dina is convinced that Ellie is immune.

In response to learning this information, Dina tells Ellie that she is pregnant. Dina shows Ellie that she has used a large number of pregnancy tests, with each one of them coming back positive. Dina also said that her period was late, raising her concern about a possible pregnancy. This is what led to her trying the pregnancy tests, with her becoming convinced that it is true. She isn't sure how far along she is, but she is definitely pregnant. This could have a massive impact on the future of the show, as Ellie will now have to worry about a pregnant Dina.

Jesse Is The Father Of Dina's Baby In The Last Of Us

Thanks To Their Previous Relationship

As it turns out, Jesse is the father of Dina's baby in The Last of Us season 2. Ellie immediately assumes that it is Jesse, with Dina confirming this. Although Ellie and Dina are in a relationship now, this wasn't always the case. Before Ellie, Dina was in a relationship with Jesse, an important figure in Jackson. Dina and Jesse's relationship has already been explored several times throughout The Last of Us season 2, with Young Mazino's character sharing scenes with both Ellie and Dina in the previous episodes.

How Ellie Reacts To Dina's Pregnancy News

She Is Excited To Have A Kid

Dina was obviously worried about how Ellie would react to the news of her pregnancy, as she decided to keep it a secret. Only learning a secret as big as Ellie's immunity gave her the confidence to tell Ellie, and Ellie seemed to take it well. Ellie immediately took ownership of the baby, saying that she was going to be a dad. Ellie even says that she, Dina, and Jesse are having the baby together, showing that Ellie is already invested in raising the kid. Ellie and Dina then have sex after learning about the pregnancy, proving that Ellie is undoubtedly excited about the news.

However, Ellie doesn't realize how much of an impact the baby will have on their journey. This challenge first rears its head at the end of the episode, when Ellie and Dina decide to head to Lakehill. Ellie tells Dina to stay behind, with Dina being insistent that she wants to go. They decide to head out together, but this could be the first in a series of conflicts regarding Dina's pregnancy.

Depending on how long Dina and Ellie are in Seattle, the progression of Dina's pregnancy could lead to more of a challenge. The lowered mobility, pains, and other health risks that a pregnancy poses could be a challenge for surviving the WLF forces and the Infected. Even if they get out of Seattle quickly, the pregnancy could still be a problem as they are traveling home. Dina's pregnancy is good news now, but future episodes of The Last of Us could use it to raise the stakes even further.

How Dina's Pregnancy Reveal Compares To The Last Of Us Part 2 Game

The HBO Show Is Far More Positive

There are several key differences in how Dina's pregnancy reveal plays out in the HBO show compared to The Last of Us Part II. In the show, Dina's pregnancy reveal comes the morning after she sees Ellie get bit. In the game, Dina sees Ellie breathe spores, forcing Ellie to reveal her immunity. Since spores don't exist in HBO's The Last of Us, this sequence had to play out differently, explaining why the timeline of Dina's reveal is slightly different.

On top of that, Dina's explanation for how long she's known about her pregnancy is different. In the show, Dina says that she confirmed her pregnancy after they got to Seattle, with her showing Ellie several pregnancy tests. In the game, Dina says that she deduced that she was pregnant a few weeks ago due to her late period. While Dina's pregnancy is played as a suspicion in the show, it is played as a lie in the game, with Ellie being upset that Dina didn't tell her before they left Jackson.

Finally, Ellie's reaction is different. Ellie reacts positively to the news in the HBO show, with her being excited to have a kid. In the game, Ellie is far angrier, and Dina is more ashamed. Ellie expresses that Dina's pregnancy is a burden, with her being mad that Dina hid it from her. This causes Ellie to be insistent that Dina stays in the theater while Ellie continues to explore Seattle. Thus, this could mean that Dina will stay behind in The Last of Us season 2, episode 5.
