Why Fans Believe Serena Joy Waterford is Pregnant on 'The Handmaid's Tale' Season 4

Serena Joy, played by Yvonne Strahovski, is the wife of Commander Fred Waterford, played by Joseph Fiennes.

In the trailer teased just before the premiere, Waterford is seen opening an envelope. Inside was an ultrasound photo which many fans believe Serena has finally managed to conceive.

But Who is the Father of Serena Joy's Baby?

  One of the final episodes of the third season gave away a potential plot for Serena Joy's character.

In season 3, episode 11, Serena Joy slept with her husband just before they arrived at the Canadian border.

But upon arrival at the border, Mark Tuello (Sam Jaeger) managed to arrest them for the war crimes in Gilead. There was also a symbolism that was shown, a womb imagery with a lamp in the middle.

However, not everyone is still convinced that Fred is the dad. 

"The fact that they're trying to make us think it's Fred's makes me think that it's not," one Redditor said. 

Another explained, "It's likely that Fred isn't infertile either, just that he has a lower sperm count and they happened to 'catch' Serena at the right time when they finally resumed marital relations."

Fans on Reddit believe that it's also possible that the dad of Serena Joy's baby is Mark Tuello, as there have been theories that suggest she had an affair with him.

The pair have been spotted together a couple of times in the past seasons and now, Tuello is someone who Serena Joy speaks to regularly.

However, it is worth noting that there's no indication that they slept with each other.

One Redditor said that it is in Tuello's nature to sleep with a war criminal.
