Babe Smith arrives in Walford after being invited to The Queen Victoria public house by Tina Carter (Luisa Bradshaw-White).
When Stan loses the use of his legs due to his prostate cancer, Tina asks Babe to visit so she can persuade him to seek medical help.
Babe continues to create a rift between the Carter family and pays a teenager to throw a brick through the window of Shirley's son Dean Wicks's (Matt Di Angelo) salon.
However, Dean's father, Buster Briggs (Karl Howman), learns the truth behind the attack and confronts Babe in front of the Carters, tipping a trifle over her head.
Linda's mother, Elaine Peacock (Maria Friedman), and her toyboy fiancé, Jason Adams (Scott Neal), temporarily move into The Queen Vic.
They later have a heart-to-heart where Babe explains that the money was placed into a bank account for Linda's infant son, Ollie Carter (Charlie) and says how she is cruel because it makes her feel better.
Standing in the rain, an angry Babe curses the Carter family, stating she hopes they lose the Queen Vic and everything else they love, before then leaving the Square for good.
"[3] Speaking of how she received the role, Badland recalled that she had previously worked with Treadwell-Collins on an independent film so she was requested for a "chat" with him, before they read through scenes from the show.
[4] When discussing plotlines for 2014, Treadwell-Collins said he wanted to see younger characters through the eyes of their parents and not the other way around and that was part of the reason behind Babe's introduction.
[7] Babe returned for the indefinite future on 3 September 2015, in a storyline which saw Shirley, Tina and Mick track her down to retrieve and scatter Stan's ashes, which she had previously stolen.
[10] Rebecca Scroggs, who plays Tosh Mackintosh, described Babe as "a lovely woman" with a darker side that could make her the "most fearsome Carter of all".

[4] Babe falls out with Mick's son Johnny Carter (Ted Reilly) when he tries to stop her plans for a night at The Queen Vic, sparking tension between them.
The next minute, she's inventing a pregnancy, having a special "Mitchell on board" t-shirt made up, and even seducing a random guy to cover her tracks.
[13] Lindsay believed that in the weeks following the scene, viewers would "laugh at Babe and Abi, cry for them, feel for them, root for them and scream furiously at them while throwing plates at [their] televisions.
[48] This plot twist was criticised by Zoe Clark-Coates, co-founder and CEO of The Mariposa Trust, who said, "To regularly see TV shows using fake miscarriages as light entertainment could make people question genuine losses.
Deen included the scene where Babe deliberately burns Abi in her list of "12 times soaps were scarier than any horror movie".
Of Mick and Linda making amends with Babe, Badland explained, "Although it might appear on the surface the Carters have forgiven her for playing a part in Abi's fake pregnancy lie and encouraging her to sleep with Lee, there could be repercussions further down the line.
"[47] The show reintroduced Mick's mother-in-law Elaine Peacock (Maria Friedman) in October 2015 and introduced her "toy-boy lover" Jason Adams (portrayed by Scott Neal).
"[22] Comparing the baby farming storyline and Abi's fake pregnancy, Brown (Radio Times) questioned Babe's "baby-obsessed" nature, writing, "what is it with her keen interest in other people's newborns?".
[21] Billy Mitchell (Perry Fenwick) discovers Les's secret, which made Kilkelly (Digital Spy) believe that "it's only a matter of time before more characters find out.
Other suspects included: Linda, Lee, Whitney, Ben Mitchell (Harry Reid), Steven Beale (Aaron Sidwell) and Lauren Branning (Jacqueline Jossa).
[74] A show spokesperson recalled that before moving to Walford, Babe was "seen coming and going from The Square with her own life" and stated that she would "still very much be in the wings" and could "cause aggro for the Carters.
"[75] Ian Sandwell of Digital Spy hoped that Babe's exit storyline would see her receive her just deserts as punishment for her "despicable schemes", but believed that she would "get away without getting a proper comeuppance.
"[18] When the Carter family begin to struggle financially, Babe decides to help by selling alcohol before the allocated hours, despite it breaching The Vic's licensing laws.
[84] Sally Brockway, writing for magazine Soaplife, wrote, "She may rustle up a mean trifle, but you'll pay the price if you get on the wrong side of Aunt Babe Smith.
"[22] She also praised the scene where Buster Briggs (Karl Howman) threw a trifle over Babe's head and said, "She looked like a creature from the deep.
[89] Babe's departure appeared in an article published by Digital Spy, which compiled ten unmissable soap storylines airing the week the episode was broadcast.
[90] Lindsay (Metro) described Babe's final episode as "dramatic" and opined that he would "certainly miss her antics and deliciously poisonous dialogue.
Finally, White said that Badland had "used every look and gesture to build up Babe's eccentric personality, and has been able to skip lightly frin dark to hilarious in a hearbeat.
