Anticipations are on the rise regarding the appearance of Betty's brother when 'Riverdale' Season 2 airs. According to a former report by J-14, Betty and Polly may have to welcome a new member of the family. The family secret is rumored to be disclosed in the forthcoming episodes.

Betty and Polly's mother had a baby boy that she had to give up for adoption. Theories are now rising implying that it would be Betty and Polly's half brother. However, no one knows his name or his location, but the series' executive producer, Roberto Aguirre-Sacasa offered some hints of his upcoming appearance when 'Riverdale' season 2 airs.

Other theories

Other theories have also surfaced regarding Betty's half-brother.

There are some rumors that point to Serpent Joaquin DeSantos as Betty and Polly's brother. Joaquin is also known as Kevin's boyfriend and could be Jughead's half-brother as well.

Based on the complicated family lineage that thrived in 'Riverdale', there is a possibility that FP Jones could be the father. If this assumption materializes, Betty and Jughead might have to face the reality of sharing the same half brother.
