EastEnders fans are set to see some very awkward encounters when Derek Branning's (Jamie Foreman) daughter Alice (Jasmyn Banks) arrives in Albert Square next week.
Derek sees that a young girl has been following him around the Square and, after his paranoia gets the better of him, he gives chase and confronts her.
Alice says that she is his daughter, and an emotionally exhausting day follows for both her and Derek.
The episode airs on BBC One and RTÉ One on Thursday May 10.
