Kate and/or her agent were very smart. When they negotiated her The Rookies contracts, she was guaranteed a Made-for-TV movie during the hiatuses (which is why she did Satan's School For Girls, Death Cruise, and Death at Love House for Spelling Goldberg - and she was quaranteed a pilot after The Rookies ended. Given that she had a supporting role, it's amazing that her contracts had better guarantees than the three male leads had.
