Dot shocked on EastEnders return
The EastEnders veteran is back in Walford after actress June Brown, who has played her since 1985, began a sabbatical in the spring of last year.
June, 85, has taken a break before, leaving for a four-year period in the 1990s.
She will be seen making her return in the BBC One soap tonight, walking into her living room to be confronted by the sight of granddaughter Lauren romping on the couch with a mystery young man.
A spokeswoman said Dot has the "fright of her life" when she walks in to find them.
