Coronation Street star Sydney Martin, who plays Betsy Swain in the ITV soap, has said her character is determined to "dig deeper" to discover secrets from the past.
Betsy's mum, DS Lisa Swaine (Vicky Myers) has been struggling after Craig Tinker's (Colson Smith) death. When Betsy catchers her mum looking through old boxes it piques her interest.
"Their relationship has often been based around lies, there's a lot of times her mum has lied to protect her but Betsy just wants to be treated like an adult now," Martin said.
"If snooping in these boxes means she can find out something that her mum's not going to tell her otherwise, then that’s what she's going to do."
Betsy's snooping leads her to finding out something about "her other mum Becky who died that leaves her wanting to find out more".
"It seems there were certain things she didn't know about her other mum and again that stems a bit of resentment in Betsy towards Lisa because it means she’s been keeping stuff from her," the soap star explained.
When Lisa tries to fob Betsy off and says the box contains details about her paternity that she doesn't want her to see until she's 18, Betsy isn't convinced.
"There’s a really nice scene where we see that paternity doesn’t matter to Betsy," Martin said.
"When you see two women in a relationship there’s often a big deal about who’s the dad. But their family dynamic isn't about that, her parents are her mums, it was just a sperm donor, that doesn’t mean anything to Betsy.
"So when Lisa tries to fob her off saying the box contains her paternity results, Betsy knows it's something neither of them really care about so she’s going to dig deeper."
After uncovering some information about Becky, Betsy and Lauren decide to go to the prison to find out more.
"They're going to visit Logan, who they know was involved with the death of both Becky and Mason, so it’s a big deal but Lauren naively thinks she can handle it," the actress explained.
"The plan is to ask questions about the night Becky died and get more of an insight into what happened but at the end of the day Logan is in prison for a reason, he’s not a very nice guy and she’s probably going to have to deal with the repercussions."
Martin, who has been on Coronation Street for a year, said Betsy has "opened a box that should have stayed closed".
"Someone in prison, convicted of attacking their own brother, is not going to help her, especially not for free," she said.
"He will want something out of it and she’s making deals with the devil."
