"We told [Eliot] on Monday. We told his dad before that obviously and checked that it was okay, but we knew that it was always going to be Bobby. But when we told him... he's so clever, Eliot! He said, 'Oh God, that makes sense. Of course Jane had to do it because otherwise Bobby would go to juvey'. He's a clever little boy!"
Treadwell-Collins also revealed that EastEnders' story producer Alex Lamb was the first person to suggest that the culprit should be Bobby.
"My idea was Jane and then Cindy," he explained. "And then Alex Lamb said Bobby. We were at story conference and we went up to my hotel room - [series producer] Sharon [Batten], Alex Lamb, [script producer] Manpreet Dosanjh and I.
"We sat there and came up with it and we jumped up and down! If you look at the pieces now, Jane took Bobby away! We cleverly, I hope, seeded everything."
