Who tried to kill Aunt Babe in EastEnders?

It looks like it's payback time for nasty pub cook Aunt Babe when she's found unconscious in EastEnders

Since arriving in EastEnders, Aunt Babe has had an unfortunate habit of upsetting people – so there’s plenty of folk in Walford who would like to see her put firmly in her place; not least the Cokers, whom Babe has been subjecting to a particularly vicious blackmail campaign.

So when someone takes revenge on the pub cook, the list of suspects is as long as your arm. But who would go so far as to attack her?
