The character was created by a team of 13 writers aged between 17 and 22 and is described as bright, sarcastic and a rebel.

Outside, she asks Peter if he knows Shirley Carter (Linda Henry), saying they go back a long way.

She is about to explain her reasons for being there when Phil Mitchell (Steve McFadden) comes in, and Shirley asks her to leave.

She runs off again and Leon, along with Fatboy (Ricky Norwood) and Mercy Olubunmi (Bunmi Mojekwu), finds her and she picks up her bags.

Knowing they can no longer stay in the flat, Fatboy offers them a room at his house.

Several weeks later, she runs away from Fatboy's house without warning, returning to Walford and spending the night at Shirley's flat.

This fails, so she asks Phil for a favour, and he speaks to the headmaster Mr Allcock (Bill Buckhurst).

Zsa Zsa receives a letter from her mother asking her to join her in Spain, but she does not want to go, so tries to prove she is useful by babysitting Shirley's housemate Heather Trott's (Cheryl Fergison) baby George and saying it is a shame after Shirley went to all the trouble to get her into school.

She starts receiving gifts from an unknown person, calling themselves "The Blue Masquerader".

They search for Leon and find his mobile phone with blood on it, leading them to believe that Peter hit him with Fatboy's van the night before.

They move in with Heather, but the landlord fails to make mortgage payments, meaning bailiffs turn up to take the house.

In 2022, when it is revealed that Tina has been murdered by Gray Atkins (Toby-Alexander Smith), Zsa Zsa's cousins Nancy Carter (Maddy Hill) and Frankie Lewis (Rose Ayling-Ellis) visit her in France to inform her.

The first is a video of her writing a text message to her mother, in which she says goodbye and that she is sick of trying to mend their relationship.

'"[6] Kenny was said to be thrilled to be given the opportunity to write and act for EastEnders, describing the programme as "iconic" and adding that her part in the spin-off was exciting as it was connecting with viewers who use computers more than they watch television.

Director Michael Keillor advised her to spend a weekend in the East End of London, listening to different accents.

[4] Kenny told magazine Inside Soap that she found her first day on set intimidating because she had an argument scene with Henry, but said that she helped her feel "at ease.

"[10] Along with her co-stars Sam Attwater (Leon Small) and Ricky Norwood (Fatboy), Kenny's initial contract was extended to six months,[11] and in May 2010, along with Attwater, it was announced that she would be written out of the show, expressing a wish to pursue further acting roles.

The new executive producer Bryan Kirkwood said "Emer and Sam have made a real impact in the short time they've been on the Square and we wish them all the best for the future.

Kenny also discussed writing the second series of EastEnders: E20, saying: "I really wanted it to start with a bang.

[7] During the development of the character, she changed a lot and was fluid until filming started, when Kenny had a full day on set with Henry.

"[7] When the character was announced, she was described as beautiful, funky, an outspoken tomboy, very bright, but likes to think she does not need anybody's help.

"[15] She told entertainment website Digital Spy that Zsa Zsa is "a real bitch"[7] and "very mean and cold",[16] while a profile for the character on the official EastEnders website says she is sarcastic, a rebel and "desperately wants the security that comes with a family but is terrified of being dependent on anyone.

Kenny also stated that her character is to be heavily involved with her on-screen aunt Shirley.

She added: "The pair recognise their similarities and that brings a warmth to their relationship.

[19] A writer for The Northern Echo wondered if Zsa Zsa, along with Leon and Fatboy, brought a new injection of life into EastEnders or took away screen time from more established characters,[20] Zsa Zsa was featured in Inside Soap's "Next Big Thing" feature in 2010, where they name the new stars of British soaps that they believe "will set the world of soap alight in the year ahead"[10] but after her departure they branded her one of 2010's departed characters that would not be remembered.
