Hook is a real jerk in this story, he isn't in the show.
Emma stood at the alter wearing a hot floor-length black and white lace-up wedding dress hands held with Hook wearing business groom tuxedos best man peak black lapel groomsmen men wedding suit.
Emma was looking down in an almost crying way, she couldn't even look at Hook right now.
Hook on the other hand was as happy as ever, he couldn't stop looking at her.
The preacher says, "Should anyone here present know of any reason that this couple should not be joined in holy matrimony."
Emma wanted to say something so bad but, hers and her really true loves life depended on her keeping quiet.
Hook looks down at Emma and smiles he is ready to say his vows and have Emma recite the vows he wrote himself.
This was not the kind of wedding Emma ever wanted to have, she didn't even get to pick her wedding dress, Hook did.
Emma hoped someone would say something.
"speak now or forever hold your peace." the preacher said one last time.
Suddenly the chapel doors swing open slamming ageist the wall.
"I object!" the voice yells, Emma whipped her head to the familiar voice.
Emma's real true love runs up the isle,
"Emma you can't marry Hook" Regina says.
"she can and will" hook bellows back.
Emma just turns her head looking right at Regina and says nothing.
"and why can't she marry him?" the preacher asks.
Regina glances back at Emma friends and family with an 'I'm sorry' peering across her face.
"she doesn't love him, and she doesn't want to marry him!" Regina yelled
"then why is she here!" Hook screamed back.
"how dare you ask that question" Regina yells back.
"how dare you come in here uninvited and say such things" Hook angrily bellows back.
"How can you even do this to her, you know she doesn't love you?" Regina screams back.
Emma then fell to her knees tears streaming from her face, her hands on her face.
"look what you did" Hook bellowed at Regina.
"Emma are you ok?" the preacher asked placing his hand on Emma's shoulder.
"Emma stand up now, we are getting married now." Hook yelled at Emma.
Still crying Emma jumped up quickly, she was scared of Hook.
"Emma come with me, you don't have to marry him." Regina explained grabbing Emma's hand.
Regina pulled Emma and Emma started to go with her when Hook pulled her back.
Hook throw his arm in the air and Emma flinched she thought Hook was going to hit her.
"Emma, come on he can't hurt you if you leave him." Regina said so sweetly.
"I can't go..." Emma mumbled under her breath.
"what" Hook grunted through his teeth.
As Regina said "what?" in question. Emma shook her head no, meaning nothing.
"I don't want to say this but, everyone needs to know..." Regina preached
"Emma's life depends on her marring Hook... He threaten her and said if she doesn't marry him he'd kill her" Regina told everyone in the chapel.
Gasps went around, as Hook said "what? What kind of bs is this?"
Hook was clearly nervous, and uneasy.
Regina grabbed Emma's arm and pulled her away from Hook and into her arms, hugging her tightly.
"Em your mine now" Regina softly whispered.
Emma cried in Regina's arms.
Hook punched Regina knocking her the floor and grabbed Emma, he started saying his vows.
At the time Regina was punched a women screamed in the chapel.
Then around 3 mins later, the cops arrived and arrested Hook.
After Hook was taken away, Regina awoke laying in Emma's arms with a crowd around them.
Emma had her head down crying, she thought Regina was really hurt or worse dead.
"Emma? What happened?" Regina whispered
"Regina your ok!" Emma smiled.
Emma then bent down and kissed Regina, thanking her for what she had done.
