We know Gabby and Liv can be trouble, but they take it to a whole new level this week when they decide to spike Daz's drink with ketamine. The pair are confused when he seems unaffected, and it's only when Lisa collapses that they realise they put the drug in her pint by accident.
Lisa is rushed to hospital, where the doctor asks if she's taken anything - and Liv fails to speak up. But when Lisa then goes into cardiac arrest, will the teen come clean before it's too late?
The Dingles aren't the only ones who've been affected by Gabby and Liv's 'prank' as Vanessa and Paddy worry what will happen if anyone finds out that the ketamine was stolen from their surgery. After all that unpleasantness with Rhona a few years back, they should really keep a closer eye on their drugs...
Elsewhere, Rebecca is devastated to learn that she may have a brain injury, Chas tells Paddy she wants to have their baby, and Joe finally realises just how dangerous Debbie can be after discovering he was the intended victim of the acid attack.
