Veronica Rocks a Wedding Dress in New Riverdale Promo

A brand new promo for the second season of Riverdale has been released. The promo features a throwback to the Archie Comics, Veronica in a wedding dress and so much more.

The new season is set to begin on October 11. I am going to guess the Veronica in a wedding dress scene might be a hallucination Archie is having.

What do you guys think is going on in the scene?
