Riverdale showrunner Roberto Aguirre-Sacasa has shared a picture of Supergirl actor Melissa Benoist visiting his set and his actors - in costume, no less. Take a look:
Benoist has been spotted on set before - however out of costume - but take the writer/producer's tease of a "crossover" with a huge grain of salt. Both shows - along with several others at CW and elsewhere - film in close proximity in Vancouver, British Columbia.
Riverdale is scheduled to begin its second season October 11 on the CW, while Supergirl's third is set to debut October 9.
