So here's the big question:
Did
Kerry Wentworth attend the FRC Holiday Celebration?
That'd make the hint make a lot more sense.
A ROSE KISSED -- Seal
SINGER GREAT -- Seal Great /
Great Seal
A DINNER MISSED -- Kerry?
HOLDING WEIGHT -- Carry
Carrying the great seal, or carrying a pyramid. This would explain all of the miscellaneous threes, as well--harking back to Triple Play.
