Days of Our Lives (DOOL) spoilers and rumors tease there may be more trouble ahead for Xander Kiriakis (Paul Telfer) when the Greenes learn he killed their grandpa!

Mark Greene (Jonah Robinson) first arrived in Salem two days after Konstantin Meleounis’ (John Kapelos) death, and may not have known he’d been in Salem.

Days Of Our Lives Spoilers – Do The Greene Siblings Even Know About Konstantin?

It’s a fair question as to whether the Greenes even know about Konstantin, although they may be aware that their mother, Cathrarina Meleounis Greene (Susan Elena Matus) came from Greece.

Considering Konstantin claimed she was dead, and accused John Black (Drake Hogestyn) of killing her, it sounds as if the two became estranged and she eventually wound up in the US.

Clyde Weston (James Read) was certainly in Salem when Konstantin was still alive, yet Weston never contacted Konstantin, although somehow he captured John when he was looking for Catharina in Greece!

If Cathrarina was estranged from her father, then the Greene siblings may have never known about him. But if she did tell them, and she now finds out he was killed in Salem, there could be revenge sought!

DOOL Spoilers – Eventually, Now That Katharina Has Been Rescued The News Of Konstantin’s Death May Affect Her

Presumably, once Katharina has gone through some healing from the brainwashing and captivity on the part of Clyde, she will settle in Salem with her children.

It can be assumed that her husband must have perished in the car accident that both she and Cat Greene (AnnaLynne McCord) were assumed to have perished in as well.

But once Katharina is settled in Salem and presumably, cleared of the attempted murder of Clyde-possibly by reason of temporary insanity-Konstantin’s name will surely come up.

And when it does, she most certainly will find out that Xander killed him-even though it was in a defensive move, and he was never charged.

Days Of Our Lives Spoilers – Will The Greenes And Catharina Make Trouble For Xander?

Whether the Greenes and Catharina will make trouble for Xander over Konstantin’s death largely depends upon what relationship Catharina may have had with him prior to leaving Greece.

They may have kept in touch and not been estranged, and Konstantin may have been lying about her death, knowing full well she was alive and living apparently in Missouri.

When he was in Salem and romancing Maggie Kiriakis (Suzanne Rogers) he did nothing but play con games, after the Kiriakis fortune.

If, perchance, Catharina and her father were separated in Greece by no fault of their own, and Konstantin thought she was dead, she may have considerable regrets.

If that is the case, she and her older children may want payback from Xander and sue for wrongful death, possibly in civil court!
