You know, originally, Sami had gone off looking for EJ, eventually finding him, but in the process, dragging her children all over the world, alienating them in a way.
And now.......EJ, her kids, all in Salem (except for non-mentioned Sydney) but Sami still goes off to Italy, I believe,
I know the actress doesn't want to be tied down to Days, so won't commit.....but if she is living elsewhere, then her visits to Salem should be related to problems her kids have. So they could have a story. These random visits really have been a dud, at least to me.
