Lots of people were left very confused by the One Of Us finale

On a day when the BBC was reeling from the loss of the Great British Bake Off, the excitement of the finale of new hit drama One Of Us just about kept people in the mood for some television.

Since it first hit our screens almost six weeks ago with a murdered pregnant newlywed couple sprawled out on the floor of their Edinburgh flat while a creepy man stood over them, people have been hooked.

As the storyline has unfolded, however, and the surprise twist revealed in Tuesday’s final episode, many people on Twitter were left with a lot of questions.

This program was so random, it was just story lines that didn't fit together. WELL THANKS FOR THAT BBC #oneofus

#OneOfUs I honestly don't get it. Who gave birth to who, do they even know?

As it was claimed that Grace and Adam were siblings, plenty of people claimed to have known all along (disclaimer: we’re still not 100%).

#oneofus yep. Bro and sis.

I KNEW it. Adam and Grace are brother and sister #OneOfUs

According to our research, this woman seems to have called it first.

#OneOfUs I think Grace and Ad are both Bill's child

The revelation drew a lot of anger for the parents for not working it out earlier.

So the mother has an affair, 9 months later gives birth, and doesn't *ever* think 'hmm, I wonder..?' #OneOfUs

So Moira knew (she must have known) they were siblings but let them just get on with it?! Wtf? #OneOfUs

But mostly people were just left confused.

#OneOfUs IF THE YOUNGEST TWO WERE BROUGHT UP IN THE SAME PLACE WHAT IS WITH THE DIFFERENT ACCENTS??
