Devious Betsy Swain (Sydney Martin) is set to cause tension between popular Coronation Street couple Carla Connor (Alison King) and Lisa Swain (Vicky Myers) as a new spoiler video shows.

The teen is currently recovering from a gunshot wound which left her unable to feel her arm – something that she has been struggling to come to terms with.

This has led her to lash out at those around her, most recently stealing Tracy Barlow’s (Kate Ford) van after confronting her about her involvement in Rob Donovan’s revenge plot.

When Rob was on the run last month, he took Tracy, Carla and Lisa hostage and threatened them with a gun.

Lisa’s detective training kicked in as she wrestled him for the weapon, but she accidentally pulled the trigger in the struggle, which resulted in Betsy being caught in the crossfire.

When Lisa admitted responsibility to Betsy, the teen was more angry about the fact that Lisa had put herself in danger, pointing out that she needed her.

‘Lisa went in to protect Carla, and Betsy loves and respects Carla, but at the end of the day she’s Lisa’s daughter, and I just think she wants her mum to remember that,’ actress Sydney Martin explained.

Betsy has continued to struggle in the wake of her injury, with doctors warning that she could be permanently paralysed in one arm.

‘She’s paralysed in the arm, so she goes back to being a bit younger and her mum really mummies her, and I think Betsy really enjoys that, because she’s getting that one-on-one time with her mum that I think she’s definitely lacked.

‘Whereas I think Carla sees it as Betsy needs to grow up a little bit! So I think it causes a bit of a strain in the dynamic between the three of them.’

However, in upcoming scenes it becomes clear that perhaps Betsy may be overplaying just how bad her injury really is…

Having been tasked with keeping an eye on Betsy, Carla is clearly growing tired of running around after her, especially as her requests become more demanding.

With Betsy distracted by the telly, she slips up when she takes the pepper mill from Carla and uses both hands to season her lunch.

As soon as Carla points out what she’s seen, Betsy sends her lunch flying – just as Lisa returns home.

Betsy storms off, as Carla is incredulous that she’s been faking her paralysis.
