Who is the father of Imogen Adams' (Bailee Madison) child in Pretty Little Liars: Original Sin? This is one of the biggest mysteries so far from the first three episodes of the Pretty Little Liars reboot. In Pretty Little Liars: Original Sin episode 1, "Chapter One: Spirit Week," Imogen goes to the school nurse's office to talk about getting an abortion. However, the nurse reminds Imogen that she is six months pregnant, which means that getting an abortion is no longer an option. Interestingly, Imogen was at Kelly Beasley's (Mallory Bechtel) party that occurred six months ago, meaning it is highly likely that the father of her child was also at Kelly's party that night.

In addition, Imogen has mentioned that the father of her child is a lifeguard. Unfortunately, no lifeguards have been shown in Original Sin so far, but there is a chance a lifeguard could show up in one of Pretty Little Liars: Original Sins' gory upcoming episodes. It's also possible that the father of Imogen's child attends a different school in the area, as people from all over the Millwood area were invited to Kelly's party. In "Chapter One: Spirit Week," Imogen mentions to the nurse that she and her mother were planning on raising the baby together, meaning that whoever the father is doesn't want to help Imogen with the child.

Imogen admitted to Karen Beasley that she kissed Karen's boyfriend, Greg (Elias Kacavas), during the events of Kelly's party. This makes it possible that Greg to be the father of her child, but this theory is unlikely as Greg isn't a lifeguard. This means it's most likely that the father of Imogen's child hasn't appeared in Pretty Little Liars: Original Sin yet. Perhaps the father will be revealed in a future episode, even though he seemingly wants nothing to do with raising the child.

Imogen's Pregnancy Adds A Unique Twist To Original Sin

Pretty Little Liars has always included family dynamics, and the fact that one of the main protagonists of Pretty Little Liars: Original Sin is a young, pregnant teen greatly increases the tension of the show and makes the drama even more real. This means that the masked "A" character is attacking and torturing a pregnant teen, which makes the antagonist even more horrifying than they already were. It also shows how sinister Karen and Kelly Beasley can be, as they attempted to publicly humiliate Imogen by dumping red paint on her head.

What makes Imogen's pregnancy unique from Allison's pregnancy in Pretty Little Liars is that Allison's pregnancy occurred later in the show when she and the rest of the protagonists were already a bit more experienced with the "A" killer. In Original Sin, Imogen was pregnant before the masked "A" showed up and began to come after her, which adds a new and fascinating dynamic to the show. It will be interesting to see how Pretty Little Liars: Original Sin handles Imogen's pregnancy in future episodes.
