Whenever there's a character returning, it always means trouble in one way or another.  In "Days of Our Lives," the return of Chad DiMera will be one to watch out for.

Here are the spoilers for Sept. 15 to 19:

Hope and Aiden

Hope's feelings for Aiden are stronger than ever. She tells Aiden about it and admits that she wants to be with him. However, she is still married to Bo, which leaves her in quite a dilemma. 

Fans will remember that Bo left Salem two years ago as he had to do undercover work in Europe. The problem is, it may take another year before Hope gets to talk to him again. According to spoilers, she can no longer wait so she will divorce her husband through a letter.

Chad DiMera is a changed man

Last week, when it was revealed that Chad DiMera will return to Salem, it was speculated that he and EJ will work together to take back DiMera Enterprises. However, this may no longer be true.

Chad DiMera looks like a changed man, making trouble left and right in Salem. First off, he is furious that EJ slept with his ex-girlfriend Abigail. Chad points a gun at EJ and threatens him. After that, Chad pays Abigail a visit only to learn that Abigail already has a new boyfriend. He then confronts Ben, the new boyfriend.

That's not all. Chad DiMera has set his eyes on DiMera Enterprises, too. According to Celeb Dirty Laundry, Chad will team up with Kate and plot against their enemies, namely EJ and Sami.

EJ and Sami

Meanwhile, EJ and Sami look like they are fixing their relationship. They share a kiss, and it looks like they might end up back in bed together by the end of the week. But Sami's family doesn't approve of EJ. Spoilers say that Roman Brady will intervene and talk to Sami about it. Getting closer to EJ is a big mistake.
