Terry Alderton, playing Terry Spraggan, made his debut in November, along with his children TJ (George Sargeant) and Rosie (Jerzey Swingler). Former Holby City actress Luisa Bradshaw-White was cast as Shirley Carter's (Linda Henry) younger sister Tina, who first appeared in November, followed in December by Shirley's brother, who later transpired to be her son, Mick Carter (Danny Dyer), Mick's partner, Linda (Kellie Bright), and their youngest son, Johnny (Sam Strike).

Dexter Hartman, played by Khali Best, is the son of Ava Hartman (Clare Perkins) and grandson of Cora Cross (Ann Mitchell). He made his first appearance on 7 January 2013. The casting and character was announced on 8 November 2012. Best was offered the role after he was paired up with Perkins at a workshop held by the producers of EastEnders. Executive producer, Lorraine Newman described Dexter as a "force of nature". Dexter comes to Walford and gets a job as a mechanic at The Arches, and befriends Jay Brown (Jamie Borthwick) and Lola Pearce (Danielle Harold). His significant storylines include his struggle to accept his estranged father, Sam James (Cornell S John) and his losing Phil Mitchell's (Steve McFadden) £10,000. More recently, Dexter has been taking an interest in Nancy Carter (Maddy Hill).

Steve Lowe, played by Michael Simkins, first appears in episode 4585, first broadcast on 11 February. He is introduced as Bianca Butcher's (Patsy Palmer) probation officer. He makes his last appearance in episode 4622, first broadcast on 15 April.

Steve first appears when he visits Bianca at her home. He later meets Bianca in the café and takes a liking to her mother Carol Jackson (Lindsey Coulson). He arranges to meet Carol, and stops being Bianca's probation officer. He tells Carol that when he heard that her son Billie Jackson (Devon Anderson) had died, he felt they had a connection, as his daughter Emily died in 1998, two days before her 10th birthday. They meet again the next day. A few weeks later, Bianca sees Steve on heading for her house, and thinks it has something to do with her son Liam Butcher (James Forde), but is shocked to find them on a date. Bianca is angry and wants Carol to end the relationship, because Steve could see something and report to Bianca's new probation officer. Carol tells Bianca that she has ended her relationship with Steve but he approaches Bianca in the market and she realises that Carol lied. Carol tells her friend Masood Ahmed (Nitin Ganatra), who tells Steve about Carol's difficult position. Steve assumes Carol has sent Masood to tell him their relationship is over and is angry with her.

Kate White from Inside Soap wrote on Steve's storyline: "Carol certainly can't be blamed for taking a liking to Steve. Not only is he a nice, eligible fella who's clearly interested in her, but they share a deep bond through having both experienced the agony of losing a child."

Kane (Harry Rafferty), Little Chris (Rizwan Shebani), Renzo (Chase Willoughby), Ali (Leanne Dunstan) and Tayo (Youssef Berouain) are members of a gang, of which Kane is the leader. The gang make their first appearance in the soap on 8 March 2013, and the storyline is the focus of a six-minute episode broadcast during Red Nose Day 2013 on 15 March. The gang's last appearance as a whole is on 29 March, but Kane appears again on 25 and 26 April. In the episode broadcast on 29 March 2013, a character refers to Kane as "Delton Kane".

The gang first appear running from the tube station, having evaded their fare. They are chased by a ticket inspector, and Liam Butcher (James Forde), who already knows them, helps them to hide. They later meet Liam and invite him to join, giving him cash and saying he will make more money than at his job. They later create a mess in the market, and market inspector Tamwar Masood (Himesh Patel) stands up to them, so they leave. They later mug him, taking his money belt, and Kane goes to Liam's house, giving him some money and thanking him for letting them know about Tamwar's money belt. Liam's mother Bianca Butcher (Patsy Palmer) finds the money belt in Liam's bedroom and is then told that Liam has been associating with a gang. Kat Moon (Jessie Wallace) tells Bianca that the police think the mugging was done by a known gang from an estate where a shooting took place recently. Bianca goes there when Liam does not come home, and sees him messing around with the gang. She confronts them, saying they bullied Liam into joining the gang and she knows about the mugging. She tells Liam to come home, saying he could end up dead. Renzo states that Liam is having dinner with him and his mother that night, but Bianca refuses to believe it. Kane threatens Bianca, eventually pushing her to the ground, which displeases Renzo, who checks if Bianca is okay. Some of the other gang members then take Liam away, while Renzo calmly warns Bianca about the area before disappearing. Liam comes home the next day and the gang arrive later on. Bianca finds them, and tries to make them stay away, while Liam has to be physically restrained by Ray Dixon (Chucky Venn) and locked in his bedroom to stop him seeing the gang. After he is let out, he returns to the gang, and they tell him to prove his loyalty to them, by walking a dangerous wall, smashing a car window, stealing alcohol and stealing money from his colleague Shirley Carter (Linda Henry). The gang then congratulate Liam for passing, by holding a party in his honour. Liam tries to leave the party after being warned off by a girl he knows, but the gang stop him leaving so he hides in the bathroom. As Kane confronts Liam, the police arrive and the entire gang, including Liam, are arrested. They are all released without charge, but the gang blame Liam. When Bianca arrives and sees them all together, Little Chris stabs Liam and they run away. Ava and Dexter then discover the gang have trashed their flat. The gang members are arrested again but as they deny any involvement in the stabbing, they are released on bail.
