Rob is currently trying to prove his worth to his sister Carla Connor (Alison King) after she sacked him from his management position at the factory.
Carla is left startled in the coming days when Rob manages to steal away some of her clients while launching his own business. However, when she finally relents and offers him his old job back, Rob ups the ante by making it clear that he wants even more responsibility.
Baylis told itv.com: "Initially she just offers him his job back, but because of the contracts that he has signed - specifically with one client - it wouldn't actually be in his own interests to simply go back and work for Carla.
"He thinks he has proved his point so much to the point that he thinks he shouldn't just have his old job back, and it is a situation that he wants to be a shareholder. He believes he is bringing enough deals to the table to make that a viable option for Carla."
The actor added: "He has a vision for Underworld that he wants to build with Carla, rather than working against her."
