The last time the soap celebrated a landmark anniversary was when the killer behind Lucy Beale’s (Hetti Bywater) was revealed.
In a series of flashbacks, it emerged Bobby Beale (Clay Milner Russell) has caused his sister’s death and having recently returned to Walford after a spell in youth offenders, the upcoming special episodes will see yet more trouble stirred up for the youngster.
Having problems with father Ian Beale (Adam Woodyatt), the teenager will come face-to-face with brother Peter Beale (Dayle Hudson).
However, having not spoken since his young sibling killed his twin, will all be plain sailing?
EastEnders continues Thursday at 7.30pm on BBC One.
