Many Rumbelle stories take place after Belle and Rumple have already undergone a terrible loss, using the hurt/comfort trope to show how they cope afterwards.

We'd obviously be bummed to lose Giles Matthey as Rumbelle's adorably evil baby boy, but at least there's still some hope that the couple can get their baby back instead of missing out on his entire life.
