Episode of BBC's hit soap shot live to celebrate its 30th anniversary
But actress Jo Joyner stumbled as she returned for first time since 2013
Instead of asking 'How's Ian' she asked 'How's Adam' - his real name
Incident prompted a flood of reactions and memes from fans on Twitter
Some suggested the mysterious Adam could have killed Lucy Beale
Actress was light-hearted on Twitter - where her co-star replied: 'I'm fine'
