Although The Witcher season 2 will abandon the multiple timelines that may have confused viewers throughout the first season, it sounds as if flashbacks will certainly play a big part in the story. According to showrunner, Lauren Schmidt Hissrich, the Netflix series' second season will have a large focus on Geralt's origins, giving us a further backstory and understanding of how the witcher eventually became the legendary white wolf.
Hissrich stated that the most important part of The Witcher for her is telling the story of Geralt, Yennefer, and Ciri coming together as a family. She goes on to explain that in order to picture a family, it's important to better understand their family origin. This is what she hopes to accomplish by exploring Geralt's younger years.
This is largely why the show's second season will be introducing the other witchers from Andrzej Sapkowski's stories. The series will be looking to explore the "family" that Geralt grew up with, including his fellow witchers in Eskel, Lambert, and Coen, as well as Vesemir, who served as his father figure. Not only will these characters likely be portrayed in the present, but Geralt's history with each of them will be explored as well.
There's no news as to how exactly this will be handled, but looking to the source material could provide some hints. Ciri and Geralt finally met one another at the end of Season 1, and we know that in the books, Geralt brings Ciri back to Kaer Morhen to train with Vesemir and the other witchers. This would provide a great opportunity to juxtapose Ciri's training with flashbacks of Geralt's training when he was young.
Despite a large delay in production due to the COVID-19 outbreak, The Witcher season 2 is still on track for a 2021 release date as far as we know. After the outbreak shut down nearly all production, and cast member, Kristofer Hivju, tested positive, the Netflix series was indefinitely put on hold.
That being said, reports have indicated that shooting could start back up again sometime soon. While we certainly want everyone to stay safe, it's also safe to say that we can't wait to check out the next live action chapter of Geralt of Rivia.
A feat only a true Dovahkiin could pull off.
