A storyline which has already begun airing on Australian screens has seen Ruby tell Romeo (Luke Mitchell) that she is expecting his baby following problems between them.
However, when Leah Patterson-Baker (Ada Nicodemou) starts asking awkward questions in an upcoming episode, Ruby is forced to tell her that the pregnancy is fake.
Breeds told TV Week of the storyline: "I think Ruby could sense things weren't right between her and Romeo. She was scared he'd break up with her.
"Leah is very persistent that Ruby goes to the doctor because of her diabetes, to check everything would be okay for the baby. When Ruby keeps putting it off, she ends up telling Leah the truth. Leah isn't happy and tells Ruby to tell Romeo, or she will."
The actress continued: "I think deep down she knows she made a mistake in lying, but it definitely doesn't come from a bad place. I think Ruby just doesn't want to be alone."
Ruby later allows Romeo to think that she has lost the baby as her deceitful behaviour continues. However, when Leah rebukes her for continuing to lie, Ruby is finally forced to tell Romeo the truth.
Breeds added: "He doesn't handle it well. Romeo feels betrayed and can't believe Ruby would lie about something like that."
Home and Away airs these scenes next week on Network Seven in Australia and late July on Channel 5 in the UK.
