"Martha's been with me for eighteen years. She's like family to me. I can't live without Martha, please.
Sis, I won't let Martha get in your way. I won't let her wander around the main house."
"Ms. Collins, I can clean the next house. I can water and fertilize the flowers. I can do other chores, and I won't show myself around you."
"Sis, I will do whatever you ask me to do from now on, please."
Rosemary could see that Serena was sincerely begging to keep Martha this time.
She could agree and let Serena be more obedient and listen to her in the future.
But as long as Martha was around, she would keep instigating Serena.
Even the most innocent and kind person would turn bad after being brainwashed for a long time.
So, there was no need for Martha to stay.
And there was no need for her to be merciful either.
"You're eighteen now; you don't need her anymore."
