In the Riverdale comics, Jughead is still going strong. There are no storylines where he meets his demise. The creators have kept him as an ongoing part of the comic universe.
One popular plot could be how they deal with the unexpected pregnancy while still in high school. They might face judgment from their friends and family. For example, Betty's parents might be disappointed at first but then come around to support her. Another plot could involve their future plans. Maybe Jughead has to put his writing career on hold to support the family, or they consider moving out of Riverdale to start fresh.
Some fanfictions portray them as being really strong together. They support each other through the mood swings and physical discomfort of pregnancy. Jughead might write about Betty's pregnancy journey, which could strengthen their bond.
Definitely. In the comics, Jughead's character took on the role of being a Serpent at some point. This development added an interesting twist to his storyline.
Jughead is not dead. The comic series continues to feature him in various adventures and plotlines. His presence remains an important part of the comic world.
