Laurel never figured out who killed Wes, which means Frank never killed Dominick, Jorge never tried to get custody of Christopher and he never went to jail. Jorge Castillo knew Annalise and Laurel were on their way to confront Xavier in his hotel so he put his plan in motion. While Annalise receives a call about Emmet's death, Laurel gets a call from her father who tells her something shocking while hinting at her son's future. When Frank bursts through the door of their house asking about Christopher he isn't worried because Connor just went to check on him but when he sees the worried look on Frank's face he follows the man up the stairs and discovers that not only Christopher is gone, but so is Connor. ~I am so sorry, I suck at descriptions~
