It was well known that no EastEnders cast member knew who killed Lucy Beale until it was absolutely vital that they needed to.
Many of them did not even know when they watched the episode live last night – meaning that this Vine is all the more special!
The TV show's official Twitter account shared a photo of the cast and crew of the soap watching the highly anticipated episode in a pub last night, here is their reaction to the reveal…
The episode was part of a year-long mystery surrounding the death of Lucy Beale. Her killer was eventually found to be her little brother, Bobby.
Tonight's episode will reveal Bobby and Lucy's stepmum, Jane's role in the cover-up as a bid to protect the 11-year-old.
