The boat party has set up lots of storylines and will see the residents left grief-stricken by the death of the child.
Nevertheless, some soap fans were left baffled after spotting a glaring error in the episode.
Viewers noticed the timings of the incidents at the boat party were off as well as characters moving to different locations.
One big error was how Ian was getting hospital treatment while Denny was pronounced dead at the scene.
Some audience members were also wondering why the characters were taken to Walford General Hospital rather than one in Central London.
EastEnders continues on BBC One at 8pm
