Step 2: Sneaky Ps. Is anchor claim FQ? If yes, move to step 3. If not, anchor must be Div. --> need to determine how they were brought into suit. If brought in by P whose present in the suit is pursuant to Rules 14 (impleader -- 3rd party D), 19, 20, 24, P may be trying to sneak in a claim she could otherwise have not made (doesn't meet 2 Div reqs). These are not allowed under Supplemental -- need FQ or Div or to drop the added claim. Stacked Ds: need FQ or Div. Stacked Ps against one D: ok to use supplemental. If no sneaky Ps, move to step 3.
