User blog comment:Tommy,Klaus&Kol2012+/Will the writers kill off michael in the midseason finale episode-the spear?/@comment-4554525-20181214045747

well i guess they are going to keep continuing this storyline

so we've got michael, lucifer is still apparently walking around, the empty creature is coming for castiel and kaia is coming for dean.

So we're dealing with 4 major story arcs this season.
