The latest episodes airing on Network Seven in Australia have seen Bianca lose her son to Sudden Infant Death Syndrome (SIDS). The devastating storyline was first rumoured a week ago.
Reports have now revealed that Bianca struggles to cope in the aftermath of her loss, initially turning to alcohol in an attempt to numb the pain she is feeling.
However, Bianca later leaves partner Heath (Dan Ewing) stunned by taking things a step further - begging him to give her drugs.
Lisa Gormley, who plays Bianca, told TV Week: "She doesn't want to get high - she just wants the pain to stop and to be completely numb. [Heath is] shocked because it's not like her - but Bianca doesn't want to be herself any more."
Although Heath may be reluctant to agree to Bianca's request, one character will supply her with drugs in the episodes in question.
Meanwhile, Gormley confirmed that it is a testing time for Bianca's relationship with Heath, as she struggles to be around him following the tragedy.
The actress said: "She just pushes away any reminder of that past life and doesn't want to have to deal with it. She goes into a form of denial, because the truth is just too hard to handle."
Home and Away airs these scenes next week on Network Seven in Australia, and in December on Channel 5 in the UK.
