you met Nick's mom and she told you she knew the truth about your mom and Nick's dad and that everything they said to Nick about her leaving him was fake. But you didn't trust her first so she gave you her number in case one day you wanted to know. And it happened. You let her in the house and she explained you everything

But now, Bea, Nick's ex gf, brought Nick's mother to the Leister's Gala and told the truth to every member of the Leister family, that Nick's grandfather did everything so she couldn't take Nick. But she told Nick's dad that Maggie is his daughter and she did a test to proove it. But they didn't know how she came in the house.. so you said it was you. Nick got really pissed at you and started walking towards Sofia. You stopped him and told him that you thought that it would help him to know the truth

-N : "You thought it would help me to know that my grandfather is a monster? You ruined everything! All our family! You ruined us!"

he walks away again towards Sofia, leaving you behind in tears. You follow him and call his name
