1. The Secret Experiment 2. O' Deadly Night 3. The Art of Murder 4. Best Laid Plan 5. Reap What You Sow 6. Head Case 7. Into the Viper's Nest 8. Death in My Hand

I can only find 8 answers. I didn't count The Sting of Death because Alden Greene is not a recurring character by the events of season 2. All main antagonists are not categorized as recurring characters too.
