What happened to all the other characters?
Like Hope and Jane and Frankie's father? And I'm sure there are more guest characters I'm forgetting but it's early in the morning and I'm not quite awake yet.
shareWell Sasha Alexander posted a photo of herself with Sharon Lawrence (the actress who played Maura's biological mother Hope) on instagram a while ago, it looks like Hope will return in a future episode...probably the one that Sasha is directing.
As for Jane & Frankie's father...well, he hasn't appeared in a long time, but since he and Angela are divorced now and he moved to another city, that gives him the excuse to not be there. I kinda miss their younger brother Tommy though, he's been gone for a long time too.
