The Teenage "Yellowjackets" Characters Next to Their Grownup Counterparts

Sophie Nélisse stars as the teenage version of Shauna. Her character is best friends with Jackie (Ella Purnell). In season one, we learn that Shauna was secretly sleeping with Jackie's boyfriend, Jeff, behind her back, and becomes pregnant with Jeff's baby. While in the wilderness, Jackie finds out and tells the rest of the group. Following a fight with Shauna, Jackie decides to sleep outside and ultimately freezes to death. In the second season, we see that Shauna feels guilty about what happened and begins speaking with Jackie's frozen corpse before she and the rest of the team are forced to eat it due to a lack of food. Later in the season, she gives birth to her and Jeff's baby, though it doesn't go as planned.
