Joe Miller returned to Broadchurch and viewers didn't know what to think

Broadchurch fans were sent into a frenzy last night when Joe Miller made a reappearance.

After he was found not guilty of killing Danny Latimer at the end of series two, Joe was banished from Broadchurch and is now working in Liverpool where Mark Latimer tracked him down.

But why was he back? And will Mark attack him now he's discovered where he is?!

I hate Joe Miller with a passion but I do not want to see a good man like Mark go to jail over him #Broadchurch
