TL;DR
>They'll recast Ralph for the first episode of season 7 to wrap up his storylines and then write him out.
>Sue will still appear throughout the season on her own. Seems like Ralph and her won't end up together.
>Ralph's season 7 storyline was a team-up with another regular to investigate the big bad. Now it's a solo story for whoever that regular is.
>They're leaving the door open for Ralph to return sometime in the future, likely played by the recast.
