In scenes currently airing in Australia, baby Rocco has finally been released from hospital after being kept in for observation following his premature birth, and the pair are adjusting to life as new parents.
The actor told TV Week that Bianca remains concerned over Heath's abilities as a parent, something that Ewing thinks is understandable: "Heath is a bit of a boofhead, so it's not strange that she should be worried... but Heath is obviously in love with his son and would do anything for him."
Ewing revealed that, due to a few niggling doubts in her mind, Bianca (Lisa Gormley) persuades Irene (Lynne McGranger) to also be with Rocco at the house, so Heath is not left alone with him.
This upsets Heath and he confronts Bianca about her lack of faith in his parenting ability. Ewing said: "She apologises and Heath is pretty receptive to the apology, and there's a bit of back and forth."
Bianca then agrees to leave the two alone, but Ewing hints that her fears may soon be justified, as he reveals Rocco ends up back in the hospital: "Heath packs up his bag and takes Rocco to the hospital, but doesn't think to tell Bianca.
"He just wants to be left to look after his own kid, and that creates tension."
Australian viewers will see the storyline next week on Channel Seven, while the episodes will air on Channel 5 in November.
