The first instalment of Death in Paradise saw DI Jack Mooney and his team investigate a stabbing.
The victim was attacked on a express bus to Honore and the murder left Jack baffled as no one appeared to have left their seat to commit the crime.
Many fans rejoiced over the return of Ardal as Jack but now the actor has hinted he could step down from the role soon.
He teased: “I think there is a shelf life.
“I mean, it’s tough. Ben did two series. Kris Marshall did three, three and a half series.”
The actor continued to Mirror Online: “You never really know from year to year and I’ve got a lot on with a stand-up tour this year.
“I couldn’t imagine doing it forever.”
It comes after viewers were left shocked to find Danny John-Jules’ character Dwayne Myers had left.
Ardal commented on the star’s departure, insisting it was natural for the cast to change every so often.
“We’re all dispensable,” the actor commented.

“Absolutely, when I heard that Danny was leaving, I thought, ‘Hmm. How will that play? How will the audience take that?’”
Areal continued to Digital Spy: “Because he’s a very popular character in the show, and he’s been there since the start as well, so there’s that.
“But we’ve seen time and time again that the show survives these cast changes.”
Danny John-Jules’ character was replaced by Shako Amos, who starred as Ruby Patterson.
Ruby is Commissioner Patterson’s (played by Don Warrington) niece who has just finished police college.

The youngest member of the team has a lot to learn as she assisted DI Jack Mooney.
The second instalment will see the group head to the zoo for their latest investigation.
“Jack and the team uncover a nest of vipers when a zoo owner is killed with a tranquilliser dart and everyone has an alibi,” the official synopsis reads.
Blake Harrison will guest star as Theo Roberts while Jonas Armstrong also appears as Dylan Shepherd.
Death in Paradise continues Thursday on BBC One at 9pm.
