He, along with his mother Glenda (Glynis Barber), made a previously unannounced return on 30 December 2016, before departing again on 20 January 2017.

Danny Mitchell first appeared when he visits his mother, Glenda (Glynis Barber), at her house unannounced.

Though she is startled, Glenda allows her son to stay with her and he soon learns that her late ex-husband Archie Mitchell (Larry Lamb) had recently been murdered.

The next day, Glenda takes Danny to Archie's obituary and gives him the address of The Queen Victoria public house in Walford where his sisters Ronnie (Samantha Womack) and Roxy (Rita Simons) live.

His cousin Phil Mitchell (Steve McFadden) is unhappy, thinking he is possibly a younger version of Archie.

Danny starts working behind the bar of The Queen Victoria where he meets Amira Masood (Preeya Kalidas).

Peggy Mitchell (Barbara Windsor) overhears Danny on the phone to Glenda and is furious, asking him to leave.

He explains he had an argument with Glenda and left home, then got in a drunken fight and was put in cells to sober up.

Ronnie tells Roxy he cannot be trusted, but he reveals Janine's plan, cementing his place in the Mitchell family.

Roxy is curious when Danny asks her for a £700 investment, which he later returns in full, having apparently made a profit.

Danny supports an emotional Glenda when she identifies Ronnie and Roxy's bodies with Jack and his brother Max Branning (Jake Wood).

Danny shows indifference to his half-sisters' deaths and asks about inheritance but is forced to end the subject when Glenda emotionally breaks down as a result of her grief.

The character is described as a "loveable rogue" and "a charmer with an eye for the ladies, while guys instantly see him as competition in the alpha male stakes.

"[2] Executive producer Diederick Santer said "Liam is a fine young actor, and a proper East Londoner, who I've been keen to bring into EastEnders for quite some time.

Perhaps he thinks a portion of that is rightfully his..." Bergin had heard speculation that his character may not be a Mitchell at all, but hoped that he is as he enjoyed being part of the family.

"[10] Simons also praised the casting, noting facial similarities between Bergin and Lamb, though she had expected a blond-haired actor to take the role.

[10] Bergin said that Danny likes Roxy but because of her money he sees it as a big game, as he is a "money-driven lunatic.

"[11] After Danny's departure was announced that Ruth Deller of website Lowculture opined that she would be glad to see him leave, as he was "introduced rather randomly, he has had little purpose ever since, other than to make everyone else's acting look better.
