"Riverdale" season 2 kicked off with a bang last week, with the mystery of Fred Andrew's (Luke Perry) shooting still unsolved. The good news is that he pulled through and the bad news is that the killer is still at large. In fact, just fresh off his attempted murder, he already pulled off the successful murder of Ms. Grundy (Sarah Habel). But what are his motivations? Why is he killing two people who are directly related to Archie (KJ Apa)? While the mystery continues to unfold this week, viewers will get to see Archie and Jughead's friendship put to the test through these trying times. Last season saw the brotherly bond that formed when Archie was there for Jughead as he experienced homelessness, and now that Archie is going through some seriously tough times, Jughead is stepping up to be the dependable best friend.

But according to creator Roberto Aguirre-Sacasa, there will be more "extreme situations" that will "reveal their true selves" this season, as told to USA Today.

General feeling of fear and anxiety

In "Riverdale" season 2, everyone is on high alert. Jughead (Cole Sprouse) is still dealing with his father in jail, Veronica (Camila Mendes) is dealing with her father's return, and Betty (Lili Reinhart) will soon meet her brother, Chic Cooper. There are a number of new faces introduced in the sophomore season of The CW show, and along with them comes some conflict. Roberto Aguirre-Sacasa told USA Today that Archie and the gang are now feeling "a palpable fear and dread...When characters are in those kinds of extreme situations, they reveal their true selves."

Archie's 'darker journey'

Roberto Aguirre-Sacasa previously opened up about Archie's journey this year as one that is "darker" and comparable to Bruce Wayne, who lost his parents in a shooting.

Despite surviving the gunshot, Fred Andrews now knows that someone evil is targeting him and his family, and Archie takes it upon himself to find out who it is and what exactly they are after. Veronica bravely accused her mother and father of being involved in the shooting, but Hermione (Marisol Nichols) warned her to stand down. Now that Mark Consuelos' Hiram Lodge is in town, it will be interesting to see how Veronica will oppose her father, given her firm belief that they are involved in the shooting of Fred, especially after Fred and Hermione's affair. "Riverdale" season 2 airs on The CW on Wednesdays at 8 p.m.
