Tina O'Brien - who plays Sarah - has revealed it will be up to her character to save everyone from drug dealer Callum's wrath, but she can only do that with the help of Kylie and as both girls have dated the rogue, they'll have to put their differences aside if they want to salvage the situation.

Tina said: "Sarah is definitely the weak link in the Platt family and it really becomes up to her to help get Callum out of their lives for good.

"Kylie and Sarah is an interesting relationship because they've never really warmed to each other. Especially with Sarah getting with Kylie's ex Callum as soon as she arrives and almost facilitating his reign of terror in the early stages.

"But something in the live episode brings them together and suddenly they have a common interest. If they can pull together they could have a chance."

However, the 32-year-old actress then hinted that it might not end well.

She told the Daily Star newspaper: "It's up to her to help sort things out. Whether she'll be able to remains to be seen though!"
