It was encouraging for Betty to find a huge clue, Reinhart said. The actress added that this could lead her character back to Polly Cooper (Tiera Skovbye) and find out who killed Jason.

When asked about Jason's killer, Reinhart revealed that at the end of every episode, she had a different guess on who the killer was. But she said she eventually just gave up because she wanted to be surprised and she was indeed shocked when she found out.

For Reinhart, it was a very satisfying ending to "Riverdale" Season 1 and the mystery. At first, the actress said she thought it was the father of one of the characters and then she thought it was a group effort of families working together.

"But it was a really good shock when I found out who it was," Reinhart emphasized. When asked about the fan theories that it was her character who killed Jason, the actress said she understands where they are coming from.

However, Reinhart finds the fan theories funny. Still, she thinks the fans are very imaginative and they are appreciating the dark side of her character and not underestimating her.

Before "Chapter Seven: Ina a Lonely Place," fans were surprised when Betty and Jughead Jones (Cole Sprouse) kissed. Apparently, the latter is not asexual like the one introduced by Chip Zdarsky in the comics.

Sprouse talked about his "Riverdale" character's sexuality in an interview with Comic Book. He after filming 13 episodes, he found it very meaningful.

"It makes sense to me," Sprouse said. "And if it makes sense to me as the person who's dumping so much time and so much argumentation into trying to represent Jughead correctly, it will make sense to other people as well."
