EastEnders fans were left in tears tonight, as Sean contemplated suicide after struggling with a lifelong secret.
The episode started with Sean calling an ambulance for Jean, before getting a gun and playing voicemails from his loved ones.
Stacey rushed to the farm and got to Jean and the paramedics, with the group then trying to find Sean.
Sean made a surprise return to Walford last week after learning his mum, Jean had been diagnosed with ovarian cancer.
Jean and Stacey found a note on the barn door that said "Call the police - do not come inside"
But they entered anyway and found Sean inside cradling a gun.
Sean kept saying sorry to Stacey and she asked him why he kept apologising, until he said: "I killed Dad, I hit him and there was a bleed on the brain and then he died."
Jean and Stacey tried to tell him things would have worked out the way they did anyway - but Sean broke down and said he was "so tired" of living.

Jean said there was lots of things that Sean didn't know about his dad - including the fact that his father had illegitimate children.
Eventually Sean handed over the gun to Jean and collapsed into her arms sobbing.
And fans were left stunned by the emotional scenes.
One said: "As someone who has felt even just a small part of how Sean does, we all need a Jean to just give us her words. Beautifully said and spoken."
A second said: "I can't cope this is heartbreaking to watch."
A third said: "Jean and Sean are breaking my heart."
And a fourth said: "Such a beautiful episode. I'm in pieces. In case anyone out there is feeling like Sean, please please talk."

EastEnders revealed that they have worked very closely with Samaritans to ensure Sean’s storyline has been portrayed as sensitively as possible.
Speaking about Sean’s storyline, Kate Oates commented: "The return of Sean Slater gives us a unique opportunity to explore two different aspects of mental health.
"On the one hand, the results of a long-term and untreated depression; and on the other, a person who has had a lifetime of trying to understand the delicate balance of their own mental health - and is coming out winning.
"The story is beautifully and intelligently played by Robert Kazinsky and Gillian Wright, both of whom cared deeply about getting it right, prompting discussion, and making a difference."
