Coronation Street‘s Tyrone Dobbs leaves his wife Fiz baffled next week with a sudden change of heart over his wayward mum Cassie.

As Cassie gleefully sets off for the park with her adorable grandson Dorin, it’s clear that she’s back in Tyrone’s good books for the first time in weeks.

Tyrone kindly gives Cassie his blessing to spend some precious time with Dorin while he’s staying at No. 9.

The happy families act is a far cry from the weeks of rows and recriminations since Cassie was caught out for poisoning Ken Barlow in February.

“When Dorin comes to stay, Tyrone has his doubts over Cassie being too involved in his care,” our Corrie insider reveals.

“Tyrone only let Cassie stay in the first place after being badgered into it by his grandmother Evelyn.

“Cassie risks causing even more drama on the cobbles this week as she continues to pursue Steve, so stressed-out Ty wonders whether he’s done the right thing.”

Next week, though, it’s all looking rosier as Tyrone decides to give Cassie a chance. With Cassie standing up for herself after Tyrone’s complaints, the moody mechanic realises it might be time to back down.

Tyrone tells a confused Fiz that he’s had a change of heart over Cassie and reckons it can only be a good thing if she spends some time with her grandson.

Dorin returns to Weatherfield in tonight’s episode as his mum Alina needs to concentrate on fixing up her home, which has been badly damaged in a nasty flood.

After a miserable few months of being blocked out from Dorin’s life, Tyrone is only too happy to step in and look after his son for a while.

“Alina calls again next week and reveals that she won’t be able to take Dorin back anytime soon,” our insider adds.

“Tyrone has to explain to Dorin that he’ll be staying on the cobbles for longer than planned. With a crowded house full of big personalities, can Ty make it work?”

Coronation Street airs these scenes on Monday, April 14, on ITV1.
