There is no „original“ with replicants. Think of pointers to the same physical entity – removing one doesn’t modify the other nor the entity. Only if the last replica is deleted, the entity is no longer accessible.
There is no “original file,” but I think I follow your question.
If you want the item that has replicants gone for good… right-click it, then hold down Option and the “send to trash” option will include the replicants.
