Viewers were left gasping in surprise as Cold Feet took a dark, dark turn this week.

Pete thought he was taken aback when one of the elderly men at the care home asked him to help end his life.

But that was NOTHING compared to our utter shock when HE DID IT.

Yes. Pete took a pillow and held it over Harry’s face until he stopped moving. And Twitter was flabbergasted.

Luckily, a moment later Harry sat up and Pete (and us) realised that he hadn’t offed him. Phew!

But it took some time until we had all settled down.

Fans have also been rushing to praise the show and actor John Thomson, who plays Pete, for the way his depression is being handled.

Oh God. No one talks about how hard it is to love someone with depression. Thank you. I am crying. I needed to watch this. #ColdFeet
