Fans of EastEnders are "devastated" that Sean has left Albert Square already.
Sean returned to Walford last week after 10 years away.
After taking Roxy's daughter Amy from school, he brought the school girl back to her dad Jack and discovered that his ex-wife had died two years ago.
After finding out the truth, it soon became apparent that Sean was struggling with suicidal thoughts.
In Friday night's episode (May 3) Sean was seen clutching a shotgun of the soap, as his mother Jean watched on.
This followed Stacey and a team of paramedics rushing to save Jean after she cut her leg on a walk.
They then found Sean on the verge of turning his shotgun against himself at a remote house.
Not to be dramatic but I am completely and utterly devastated that Sean has gone already.
In an emotional scene, Jean gently talked to her son as he hovered on the verge of taking his own life.
Jean, suffering from cancer, told her son that he needed to forgive himself for his past violence, and reassured him: "Whatever you’re feeling right now. It will pass."Fans praised Gillian Wright, who plays Jean, and Rob Kazinsky, who plays Sean, for their role in the emotional episode.
In last night's episode (May 7) Jean wanted Sean to move into a flat nearby, however, he made plans of his own.
Although Jean was devastated that her son was leaving, Sean told her he was going to get help.
Before Sean left, he set Jean a ringtone of 'Alright' by Supergrass so she knew when he was calling.
Sean also promised to take Amy to Ibiza when she was 18 to see her mum's bar.
Jean wasn't the only one left devastated as fans were clearly upset about Sean's departure.
After last night's episode Rob Kazinsky posted a tweet to his official Twitter account.
The tweet read: "Thanks for watching Sean this week and thanks for @bbceastenders for having him. Thank you all for watching. Just to share some final thoughts on the storyline and why it's so important to me." and attached a link to his personal message.
In the message, Rob explained: "The entire Sean arc for me is about asking for help. We are afraid to admit weakness, we see asking for help as being weak but it isn't, it takes enormous strength to ask for help."
