Did they forget about last season already
This is how they’ve written every season since the end of 3A. They pick up the very last thread of the previous season (going home, Elsa in SB, Dark Swan) and then carry that thread through to the next mini arc but don’t bother returning to any other big questions/themes, ect. It’s the same reason why Emma is still an petulant 3 yr old who complains about her walls.
