My hope is that with Rumbelle separated, they’ll take the opportunity to build on her character as a strong individual. If Moe sees her like that as well, it will likely be a revelation to him that she is actually very capable of making intelligent decisions for herself, (and for others, depending on what role she ends up having in SB), and is able to look after herself emotionally. He’ll no longer be able to look at her as his baby girl who doesn’t know what she’s doing when she wants to be with the dangerous guy. That new respect he could find for her could lead to them being able to reconcile.
