Coronation Street viewers learned Spider was an undercover police officer in the latest episode.
Now, actor Martin Hancock has spilled there will be a "powerful" backstory behind his secret career, that may be unexpected to viewers due to his past.
Spider's recent returned appeared to tie in with protests going on, as he kept up the activism viewers have always known him for.
But now it's been revealed there's more to it, amid his recent plans, and on Monday it was revealed he was a Detective Constable - something he had kept to himself.
Revealing he was working on a case, he met up with DS Swain who exposed his role with the police - as he told her to keep her voice down.
As Spider was asked for information on Toyah Battersby, amid her trial, he was left in a predicament about his loyalties.
Now, speaking to The Mirror and other press, actor Martin has revealed the truth will be told about how Spider ended up working for the police.
He hinted there was a backstory behind it all, hinting at big scenes to come.
Martin revealed: "It's just progressing the character and creating new ideas for the character. He is still a very, very committed activist, but he's doing it now from inside the system.
"It's a strange one because there comes a point when you think well, can I get more done within inside that system? I did wonder what the backstory was.
"I can't give too much away. There's quite a powerful backstory as to why Spider joined the police. It's very powerful actually. In my mind, it works, even though he's had a few run-ins himself."
Martin went on: "There's a few issues in the world today which we're going to address. There is quite nasty stuff going on. We're gonna start dipping into some of that, but at the same time as he's still Spider.
"He's still Spider, he's just getting a bit more radical in a way as what he's doing is going after some really dangerous stuff."
Coronation Street airs Mondays, Wednesdays and Fridays at 8pm on ITV and ITV Hub.
