- The theory that Miss Fluffy was Joan and Gabby's daughter. Even setting aside the fact that that would mean Derek was seriously crushing on his cousin. we eventually meet her (still-unnamed) parents. Neither are Gabby or Joan.
- The theory that JJ stood for "Joy Jr." We know it's not "Joy" anything, due to JJ being Isaac's daughter from a previous relationship. She was "JJ" before Isaac or Joy even knew she existed.
YMMV / Nicole and Derek
