'Riverdale' dropped some surprise footage of the third season — and it looks creepier than ever

• "Riverdale" just started filming season three in early July, but they surprised fans with new footage on Sunday at San Diego Comic-Con.
• The video was mostly a recap of season two, but at the very end, some new scenes were shown. 
• "After the worst summer ever, I want us to have a great, normal Labor Day weekend," Archie says to Jughead, Betty, and Veronica. 
• A clip of them driving in Archie's jalopy is shown and is followed by another scene of them swimming in what looks like a pond. 
• But the clip gets creepy at the end, as Betty stumbles upon her mom and Polly holding the twins up around a fire. 
• "Riverdale" returns to The CW Wednesday, October 10 at 8 p.m. ET.
