Hi, Lori, and welcome back to ATWT! There are probably some members who will chime in that know more than I do and can fill you in better, but for now, to answer your question, yes, Margo and Tom are still there, in fact, Margo is hot on the trail of a killer. And yes also to the question about the Snyders. The whole family is a big feature of the show lately.
You can check out the daily recaps I've been doing that cover the last few weeks, that will bring you up to speed.
And welcome to our board!
