Coronation Street viewers couldn't believe how quick Sarah Platt was to believe Lydia Chambers over her own husband Adam Barlow.
The latest episode of the ITV soap saw Lydia claim she was having an affair with Adam, leaving Sarah heartbroken.
She'd framed Adam and left a mountain of evidence suggesting there was something going on between them, and sadly Adam's word was not enough to convince Sarah she was lying.
From receipts to hotel visits, and the lingerie and oysters referenced on Adam's credit card statement, Sarah fell for Lydia's lies and kicked Adam out.
Adam told Sarah it was not true and that Lydia was clearly against him, but Sarah refused to believe him.
Fans did not understand this though, as they believed it was obvious Lydia was lying.
Not only that, but they recalled a storyline from just weeks ago where Adam was being terrorised by a mystery stalker.
Of course fans know his tormentor is Lydia, and it was all part of her plan - but no one else knows this.
So when it all kicked off on Friday, viewers didn't know how Adam had failed to work out Lydia was behind the torment weeks ago.
More than that, they were stunned Sarah was willing to believe Lydia over Adam, and despite Adam's protests she failed to realise it was linked to the recent goings on.
Taking to Twitter, one viewer said: "So weird things been happening to Adam, plus the bad Adam reviews, etc etc but Sarah is of course going to believe her over him and really not think that none of it is odd."
Another tweeted: "Sarah and Adam have suffered harassment and abuse (and crime, IIRC) at the hands of an anonymous stalker for months. Not sure why they're so slow to put two and two together..."
A third agreed: "How about working out Lydia's the stalker?" as a fourth said: "Corrie why the f**k has Adam not clicked that Lydia must be the stalker? Call yourself a lawyer solicitor or what ever you're supposed to be lol."
Others were more confused about Sarah choosing to believe Lydia straight away, with a fan writing: "Sarah, wake up. Lydia is a psycho."
A second viewer added: "Sarah is so quick to believe that Lydia is having an affair with Adam & I hope even when the truth comes out that he dumps Sarah once & for all."
Another added: "This just proves how deluded you are Sarah. Adam seen through Lydia straight away."
