Some viewers of EastEnders were left confused at the end of last night's episode thanks to a live scene where actor Jake Wood appeared to fluff his big line.
In the final moments of the episode, Lauren Branning was shown leaving in a taxi having exited claiming to know who Lucy Beale's killer was.
Afterwards in a live scene Abi Branning insisted Lauren would return shortly, but Max Branning told Abi: "She knows, she knows whether you killed Lucy."
Jake Wood, who plays Max, appeared to mumble the line slightly though, causing panic and confusion amongst some viewers.
On Twitter, Tasha Await said: "Just had to rewind eastenders like 37484 times to find out if max said you or who."
Samantha Bacchus said: "Well, I didn't have to rewind that a dozen times to figure out what Max said #EELive"
And Abi Nicholson said: "Ok, I've just had to switch subtitles on and rewind to figure out if Max said 'who' or 'you'. What the heck!! #Eastenders"
One user also tweeted: "Did that say who killed lucy or you killed lucy? #WhoKilledLucy #EastEnders #EELiveWeek (sic)"
While another added: "@mrjakedwood just wondering did you meant to say you.. or was it who.. slightly confused (sic)"

An EastEnders spokesman insisted Max got his lines right and said the wording in the script said: "She knows that you killed Lucy", meaning he only added the word 'whether'.
Bookmakers Ladbrokes reacted by cutting the odds on Abi Branning being Lucy Beale's killer from 8-1 into 4-1.
Spokesman Jessica Bridge said: "It is hard to know if Max fluffed his lines or not, but punters believe it could be Abi and have caused her odds to crash."
The shocking moment was the first cliffhanger of what is set to be an explosive week, and followed his other daughter Lauren leaving after discovering who had murdered Lucy last Easter.
There's still a long way to go before all is revealed, but this has certainly give us all plenty to think about as the soap's 30th anniversary celebrations continue.
Before this moment, we saw bride-to-be Jane Beale open a card from Abi which made things even more cryptic and confusing as the live episodes roll on.
It read: "I know what happened to Lucy. She was killed at home. Lauren"
Given the way the episode ended, this leaves the Brannings and Beales as the lead suspects - but anything could happen before the investigation comes to an end.
