And it depends on how one defines "together". Marten is at least somewhere he's content, and aside from Claire not having a job in her field yet (and he's heavily invested in her happiness), he's in a good place. And his contentment, and being centred probably does help her feel better in the now, even if she still stresses about her future.
Hanners, as well, seems pretty together these days, and, if my own experiences with exposure therapy and contamination issues are any analogue, probably isn't overly troubled by them on a constant or possibly even daily basis.
Faye and Bubbles seem to be in a good place both as a couple and within themselves, work fears and stresses notwithstanding.
Sam,[1] Jim, Veronica, and all of the characters currently taking an extended bus trip also seem to be in fairly good places with themselves.
One doesn't need to have everything perfect, both in their lives or in themselves to be "together", even if there are struggles, whether persistent or intermittent.
