EastEnders actress Lorraine Stanley has said that she hopes the soap introduces Bernie's absent father in the near future.
Little is known about the fathers of most of her character Karen's six children, although the now-established character Mitch is known to be dad to both Keegan and Chantelle.
Keanu's dad Shane was sent to prison after attempting to kill Karen with a kitchen knife, but the show has yet to delve into the paternity of Bernie (Clair Norris) or twins Chatham and Riley.
"It would be interesting to see the history of that situation," Stanley told the Radio Times. "There is still so much that is unexplained. We've talked about Keanu's dad Shane, who went to prison after attacking Karen. We know Mitch, Chantelle and Keegan's dad.
"I'd love to do more stuff with Bernie. Clair Norris who plays her is brilliant and it would be nice for her to explore that for the character. Karen has had quite a past hasn't she, there are so many skeletons in that closet of hers. About 10 dads, 50 exes. They could all come in!"
Karen currently finds herself in a love triangle with Billy and Mitch, both of whom are competing for her affections, while son Keegan is having marital troubles with Tiffany.
