Revenge season 4 returns this Sunday after a brief break as fans will be excited to now how Emily Thorne will react to Jack Porter, when he tells her: "I love you since childhood".

In the previous episode, fans were baffled to see Ben and Emily kiss right in front of Jack. This would push Jack to reveal his true feelings for the former Amanda Clarke.

However, it remains to be seen, how Emily will react to Jack's feelings for her beyond friendship. But even if she gives her nod, the couple may not lead a "happily ever after life", as the count of enemies has grown more than ever for David Clarke's daughter.

After dealing with Victoria Grayson for three long seasons, Emily will face her biggest threat in Margaux, who is carrying Daniel's baby.

Margaux is of the impression that her baby's daddy was killed by Emily and she will vent her anger on Thorne by digging deep into her past secrets.

The official synopsis suggest that Daniel's baby's mother will be successful in her effort as Emily and Jack's friendship will take a drastic turn.

The official synopsis of the episode reads: "When Margaux uses her ammunition against both Emily and Jack, their friendship takes a dramatic turn."
