Mandy Dingle has returned to Emmerdale with a bang - and a secret 16-year-old son.
We've yet to discover who Vinny's father is, but the soap is dropping major hints it's Paddy Kirk.
But despite Vinny's obvious resemblance to Paddy, viewers aren't convinced.
There have been cries of "too obvious" and "they'd never do that to Paddy and Chas".
And some even think there's another potential daddy in the mix: Marlon Dingle!
Marlon and Mandy are cousins - but she married her cousin, Butch Dingle - and being related has never stopped a Dingle before!
Fans have aired their theories on Twitter:

Yesterday, Mark Charnock, who play Marlon on the ITV soap, teased on Lorraine, fans can expect Lisa Riley's Dales comeback plot to be exciting.
He said: "The bits that I've shot with her are revelatory. There are a lot of twists and turns to come, because of Mandy. God dammit.
"I can't say too much because there are a lot of assumptions made on Twitter about why she's coming back.
"It could be that [he's Paddy's son] but it could be something else, much more significant. So we'll have to see."
And Lisa Riley (Mandy), appearing on This Morning, said Vinny "might not be" Paddy's son.
But there were some who came up with an even more crazy theory: Sam Dingle could be the dad!

Others just think Marlon's known about Paddy's secret child all along...
And there was also predictions of an illness storyline for Vinny.
So many questions!
In tonight's episode, an hour-long special, we might just get some answers...
