Bosses at the BBC soap recently confirmed that Janine is to be reunited with her maternal grandmother Lydia Simmonds, a woman with a reputation for nasty behaviour among her neighbours.
In the build-up to Christmas, fans saw Janine at the centre of a dramatic love triangle alongside husband Ryan and his secret lover Stacey Branning. Since then, she has played a significant role in Whitney Dean's sexual exploitation storyline, sending the troubled teenager off the rails while they were flatmates.
Speaking to Inside Soap, EastEnders' executive producer Bryan Kirkwood commented: "After the stories she's had lately, it's time for Janine to have some fun, I think.
"We've got Margaret Tyzack with us now, filming her first scenes as Janine's wicked granny Lydia Simmonds. I reckon it's a meeting of the minds - and a glimpse into the future for Janine!"
Meanwhile, Kirkwood also hinted at surprising developments in store for troubled mum Heather Trott, who has experienced a tough time in Walford lately.
He said: "Heather will find love with a mystery man whose identity will shock everyone. You might even know him already."
