There are some combined Brooklyn 99 thoughts that will not leave my head:

  • We’ve never met or heard about Gina’s father
  • Gina and Jake were childhood best friends, the Linettis and Peraltas were close
  • Gina bears a strong resemblance to both Jake and Katie Peralta
  • There are at least two other Peralta half-sisters unaccounted for

Could it be…?
