That's not how it works. Step siblings only occur through marriage. What you're referring to is half siblings, and even that doesn't apply to Betty and Jughead. Yes, Betty and Jughead will share a sibling. Chic would be their half brother, but Betty and Jughead would still be unrelated, both legally and biologically.
