After the season 3 finale, Hayley is on the run with Hope, desperately trying to find a cure. Four out of the five Mikaelson siblings are in a deep sleep induced by Freya to keep them alive and Klaus? Klaus is suffering alone, hidden away from the world and his family by Marcel after giving up everything for his family. This is how the Mikaelsons find their way back to each other.

Set the night Daniel finds out Margaux is pregnant he ends up drunk at night knocking on Emily's door, but will she let him in? what could he possibly want from the one woman who caused him so much trouble in her quest for revenge, and who he almost killed when he had learned she had lied about being pregnant to him? And will Margaux survive Louise's own revenge? Daniel/Emily

Now that Daniel knows Emily's real identity, all bets are off. My version of what I would like to have seen happen starting in Episode 4x8 after their spark was re-ignited in the elevator. [Demily all the way.]
