5559: Heath and Bianca have a decision to make

April and Dex walk in on Bianca and Heath kissing. April immediately becomes concerned with the impact this new relationship will have on her sister. Convinced that Heath isn't able to commit to Bianca the way she needs, April vents to Dex, who disagrees - believing that Heath has changed. However, when April persists, Dex shocks her by suggesting that the problem isn't that Heath can't commit - it's that he couldn't commit to her.

In the meantime, Bianca and Heath are still unsure where they stand with each other. Heath decides to stay away, worried that Bianca is only interested because they have a kid together. But when she turns up on his doorstep, ready to clear the air between them, both need to decide what they want to do with their future.

However, things are only made worse when Harvey tells Lottie that she has to choose who she wants to live with - him or her mother?

Elsewhere, when John picks up that Gina is trying to make Jett feel at home, he learns that it's a ploy to convince Jett to stop looking for his real father. But Jett's dream of finding his dad isn't dead, and Gina starts to feel guilty that she is being selfish.
