As for what really happened the night Denny sadly died, viewers will remember how Ian had locked him in a room on the boat to teach him a lesson for having his son Bobby Beale (Clay Milner Russell) attacked.
When the boat crashed, Ian tried desperately to save him, smashing the locked door through with a fire extinguisher, but Denny couldn’t get through the hole.
Ian has kept his deadly secret to himself, with everyone on Albert Square believing he was a hero for trying to save Denny.
In scenes set to air later this year, Sharon will discover the truth about what really happened that night.
EastEnders returns Monday at 8pm on BBC One.
