When everything seemed quiet and happy at last after the gang took down The Farm, there was a flashfoward moment.
Here, Betty, Archie Andrews (KJ Apa) and Veronica Lodge (Camila Mendes) were all standing around a fire in the woods in their underwear.
They agreed to never speak of this moment again and threw Jughead’s beanie hat into the flames.
In series four, Betty was once again seen sneaking into her house after coming back from the woods still in her underwear when she was confronted by mum Alice Cooper (Mädchen Amick).
These scenes where actress Reinhart had to be seen in her bra and knickers were the ones which were the most difficult for her to do.
