EastEnders villain Stuart Highway (Ricky Champ) was found bleeding and unconscious in the kitchen by his brother Halfway (Tony Clay).
Stuart had been shot in the stomach by a mysterious person, and the Carters immediately became suspicious of each other.
The EastEnders cast member has been left fighting for his life, and police are keen to find out who tried to kill him.
While nearly every Carter is a suspect in the shock shooting, fans think it is someone that no one has thought of.
They have taken to social media to predict it was Tina’s (Luisa Bradshaw-White) ex Sonia Fowler (Natalie Cassidy) who shot him.
One posted on social media: “Anyone else reckon the shooter person might be Sonia or Dennis? Cause Tina went to Sonia about Stuart when she remembered and where exactly is she?”
Another added: “My money is sticking on Sonia.”
A third chipped in: “Sonia fits somewhere into this storyline…I remember spoilers saying she was going to be involved with Stuart in some way.”
A fourth wrote: “It isn’t going to be any of the Carters is it?”
Is Sonia going to be the one who shot Stuart?
Meanwhile, he is set to take a turn for the worse as he is still unconscious in hospital.
The police are determined to find out who tried to kill him, but will they get the right person?
EastEnders continues on Monday at 8pm on BBC.
