Martina is an old friend of Kat Moon's from her time in Spain, but there's some bad blood between the pair because Martina was the person who reported Kat and Alfie to the police for their dodgy dealings abroad.
Following her arrival, Martina reveals that she felt pressured into grassing up the couple after the police smashed up her bar - leaving her worried that the authorities could go one step further and take Shenice away from her if she didn't reveal the truth.
Fortunately for Martina, Kat is in a forgiving mood and she soon lets her old mate back into her confidence - explaining her recent devastation over Tommy and the impact that it's had on her.
As Martina and Shenice become a regular fixture of life at the pub in the following days, will having a youngster around brighten up Kat and Alfie's lives or merely prove a painful reminder of what could have been?
Martina is played by Tamara Wall and Shenice is portrayed by Lily Harvey, sister of former Walford actress Lacey Turner.
