Mabel is actually Soos's long-lost sister! Think about it, we never see Soos's dad and we don't see Dipper or Mabel's parents! What if Mabel- and Dipper were related to Soos! Think about it! The dad and mom of Mabel and Dipper could actually be Bill Cipher's long lost parents too, as we never see his parents! And what if the Pines father is actually that random baby from A Tale Of Two Stans- oh wait, that one is a theory with actual evidence.
