Lynsey becomes "determined to find the evidence" she needs to expose Silas, entering into a game of cat-and-mouse with the murderer, who begins trying to send her mad so no one will listen to her claims.
The character also had brief relationships with Malachy Fisher (Glen Wallace), Gilly Roach (Anthony Quinlan) and Riley Costello (Rob Norbury).
On 9 April 2013, Hassan announced that she would return to Hollyoaks as a ghost or in a vision during a storyline involving the wedding of Doctor Browning and Mercedes McQueen which also happens to be on the first anniversary of her death.
Following her exit Hassan received a large number of messages on social networking site Twitter and was also praised by her Hollyoaks colleagues.
[1] Hassan told Dawn Collinson from the Liverpool Echo that once she had completed the five episodes, she returned home to Belfast where she appeared in various television and theatre productions.
[1] In June 2010, Kris Green from Digital Spy reported that Hassan would join Hollyoaks in August, as part of an ongoing rejuvenation of the serial.
He then revealed that he had been thinking along the same lines and told her that she would be a major part in an upcoming storyline featuring Silas Blissett (Jeff Rawle).
[5] A writer for E4's official Hollyoaks website said viewers should not let the character's "delicate exterior" fool them, as beneath it she had "the heart and courage of a lion".
They added that the attack marked the beginning of a dangerous game of cat-and-mouse that led to Lynsey losing her friends, job, home and nearly her sanity.
Quinlan told Inside Soap journalist, Steven Murphy, that Lynsey is "looking pretty good when she turns up" and she would eventually end up "hopping into the tub and dragging Gilly in there fully clothed!
[10] Hassan revealed that executive producer Paul Marquess brought her into his office to tell her that she would be involved in a "really big storyline", which he outlined to her, leaving her really excited.
Hassan revealed that her character is not "thinking straight" and even though it is her job to save lives, Lynsey can not decide if she should come to the aid of the person who attempted to kill her.
[20] Silas begins messing with items in Lynsey's home, which is part of his plan to alter her reality so that "when she insists one thing is happening, it appears not to be the case the next minute".
[29] Hassan explained that Lynsey does not cope with the challenge very well as she has already been pushed to breaking point over recent months and now she is trapped having to play Silas' psychotic game.
[23] At her "lowest ebb", Lynsey confides in Doug Carter (PJ Brennan) whose girlfriend, Jenny (Daisy Turner), was killed by Silas.
Silas kills a woman dressed as Catwoman, initially believing it to be Lynsey until he realises it is his daughter, Heidi Costello (Kim Tiddy).
[6] When Mercedes begins working at the hospital as a cleaner and becomes involved with Doctor Browning (Joseph Thompson), Metcalfe explained that the pair go through everything which is a "real ride of emotions".
[38] Hassan felt that her alter-ego is happy to keep things a secret between her and Riley although when Mitzeee discovers the relationship Lynsey is on the "receiving end of a lot of jealousy".
[40] Daniel Kilkelly from Digital Spy reported that the "dramatic cliffhanger" would start a whodunit storyline, as many characters had a motive to kill Lynsey.
[40] In the run up to her demise, Lynsey was attempting to discover a secret shared by Ally Gorman (Dan O'Connor) and Walker (Neil Newbon).
She also learned that Mercedes had been stalking Mitzeee and stabbed herself to frame her rival and Will Savage (James Atherton) secret story of Silas.
[40] After Lynsey's exit, Hollyoaks released a promotional image featuring her with the main suspects for the murder; Silas, Mercedes, Will, Sampson (Sean Cernow), Walker and Ally.
[41] Hassan said that she was often asked if she planned to stay with the serial and although she already knew she was leaving she had to "play along with things" and keep her exit a secret to maintain the "big shock factor" she wanted.
She touted the scenes as "really juicy, [...] very traumatic and tumultuous" and refused to confirm whether they would be depicted as flashbacks or previous events in Lynsey's life.
At Christmas, Doctor Browning turns up at Mercedes' door and explains that he was cleared of murdering Lynsey after blaming Riley Costello (Rob Norbury).
A year later in September 2013, Riley's name is cleared when Doctor Browning confesses to Lynsey's murder after being arrested for shooting Myra McQueen.
[45] In Digital Spy's end of year reader's poll for 2011, the Silas plot, including his feud with Lynsey, won Best Soap Storyline.
[1] Anthony D. Langford from AfterElton commented that Hassan's performance as Lynsey throughout the storyline was "effective" although he believed that her character had become a "little too whiny at times".
columnist said that Lynsey and Mercedes are "the unlikeliest couple of 'bessie mates'" in the serial, but felt the pair proved themselves to be "Merseyside's version of Thelma and Louise!
[59] Hassan told Digital Spy's Kilkelly that she had received a high volume of messages via social networking site Twitter in response to her exit.
