Bold and the Beautiful's Luna branded 'diabolical' as she exposes her own 'twisted mastermind' plan

Luna (Lisa Yamada) is absolutely not the "innocent" girl many believed she once was.

On the Tuesday, August 27 episode of The Bold and the Beautiful, Luna revealed to Steffy (Jacqueline MacInnes Wood) how she made sure the paternity test showed that Bill (Don Diamont) was her father and why she decided to kill both Tom Starr and Hollis .

Luna saw that Bill started to get close with her mother Poppy (Romy Park) and asked them when they met. Because the timeline added up, she kept bothering her mother and made her believe that Bill could have been her father after all. Luna knew that a man like Bill would need proof so she ordered a paternity test from the dark web.

Even though her Aunt Li (Naomi Matsuda) administered the test, luckily for Luna, it was the exact same one she ordered that was positive and she switched them. Bill was ready to made Luna a Spencer, meaning she would be set for life in regards of finances, security and care.

When Tom came out of the blue claiming to be Luna's father, Luna decided she had to take "extreme measures." Luna admitted to Steffy that she knew Tom was her father after reading the letters that she had been reading for years, despite her mother thinking Luna didn't know about them. Luna was "mortified" when she found out where he worked because she knew he wanted to tell her the truth. She put a powdered substance into his blue energy drink before his performance, where he collapsed and died.

After Luna found out that Hollis knew about Tom being her father and the letters he had written her, she could not have risked for him to spill the truth. Luna put the same powdered substance in his coconut drink, where he then collapsed and Luna just walked away while he was dying.
