Chloe's brother Aaron Brennan (Matt Wilson) and his husband David Tanaka (Takaya Honda) later ask Lisa if she would have and co-parent a child with them.
David's father Paul Robinson (Stefan Dennis) is against the idea and asks Lisa to put a stop to it, as he does not want the boys to get hurt.

Emmett struggles to make friends, but he impresses classmate Louis Curtain (Declan Dennis) when he takes the blame for trashing a school classroom.
Emmett suffers a fracture in his neck and some swelling on his spinal cord leaves him unable to feel his legs, but David assures him and Aaron that he will be fine.
Brent - who was also living with David and Aaron again - runs away, so Paul comes into contact with Jenna and requests for her to take full-time care of her son again, feeling that would be the right decision for Emmett.
The following year, Louis tries to impress Zara Selwyn (Freya Van Dyke) and friends by throwing sugar packets across the room at Harold's Café.
Toadfish Rebecchi (Ryan Moloney) comes over to speak to Zara and takes the jar of packets away, telling Louis that he has had enough target practice.

The following day, Pierce Greyson (Tim Robards) asks Rose about cutting her treatment sessions short and tells her to call the spa manager to sort things out.
A writer for the publication said Nathan would have a connection to Levi Canning (Richie Morris), and his "sexy swagger" would also attract the attention of Bea Nilsson (Bonnie Anderson).
