Kathy Beale (
Gillian Taylforth), unaware of the recent death of
Lola Pearce-Brown (
Danielle Harold) the previous day. The sisters achieve romantic attention from
Bobby Beale (
Clay Milner Russell) and
Freddie Slater (
Bobby Brazier). Anna decides to hire a private investigator to find where her mother Rose Knight is. George and Gina have a very bad reaction to this news, so Anna fires him.

Cindy Beale (

Ian Beale (
Adam Woodyatt) – Cindy's ex-husband who she has reconnected with over the past year – sees the left voicemail and deletes it once
Peter Beale (
Thomas Law) had seen it. Peter returns to the square for Gina and Anna and they briefly interact. Cindy follows Peter back to Albert Square and she is re-united with Gina and Anna in a public reveal in front of the residents in The Queen Vic. Everyone in The Queen Vic gossips and learns of Cindy's backstory and they later find out Cindy had taken the identity of "Rose Knight" and emigrated to
Marbella, where she had Gina and Anna. Anna struggles to come to terms with Cindy's nine year absence and strides along with Gina to Peggy's wine bar. She bumps into Freddie and has sex with him in the fish and chip shop owned by Ian. Ian learns of Freddie's deceit and fires him before revealing to everyone in The Queen Vic about their one-night-stand. Gina punches Ian for badmouthing Anna and Bobby is inconsolable. Bobby does not talk to Freddie and Anna for quite some time. Anna supports Freddie when he meets his rapist father

Both of them go out for a meal with Cindy, Ian and Peter. They believe it's a dinner date and it goes well until Bobby orders lobster and Anna discovers the lobster is boiled alive. Anna and Bobby take the lobsters and free them back into the sea. They plan to go onto another date but Cindy does not approve and is not willing to warm to the idea of Anna and Bobby dating after Bobby killed Lucy in 2014. This does not affect the way Anna perceives Bobby as she tells Elaine she has feelings for him. Elaine jokingly tells her to marry him and they both kiss in front of their families. Anna supports George throughout the baby farming revelation. It is later revealed that George's adoptive father
Eddie Knight (
Christopher Fairbank) murdered George's biological father in a racially aggravated attack almost 40 years prior. Eddie and his wife
Gloria (
Elizabeth Counsell) invite George along with Elaine, Anna and Gina to a party at their apartment, where Gina quickly picks up that George, Anna and herself are the only black people there. One of Eddie's friends reveals to George the true intentions of Eddie's motive – a positive character statement to prove he's not racist and taken George in by the kindness of their heart. This causes a huge revelation in The Queen Vic that causes multiple arguments within the family. Anna and Gina argue over their experiences of racism, Anna stated she is the exact same heritage as Gina. Gina then tries to make Anna realise that because Gina didn't bleach her hair nor take after her mother, she experienced a heavier tone of racism. Anna argued this – Gina mentions the difference in treatment they receive from Eddie. Eddie said Gina's hair needs to be "tamed" and continuously makes racist comments towards her that is always brushed off by George. The girls learn of the ordeal currently going on in their family only days before the trial. The family attend Eddie's trial to support George. When leaving the court room, George is encouraged to go after Gloria. He finds her but she has had a heart attack and is laying unconsciously on the floor. Gloria dies in hospital and Eddie bans George from the funeral – Anna catches wind of this and contacts Eddie to try and see if he would give any information on Gloria's funeral date, time or location (Eddie favourably treats Anna better as she is perceived to act more white whereas Gina is of darker complex).
