Charlotte Allison looked at the band-aid on her right index finger and replied, "I had someone send Hazel Allison's sample to you."
Hazel Allison couldn't wait to have people spread the false relationship between Mrs. Sheldon and herself, looking for an opportunity for the Sheldon Family to authenticate her identity and join the family.
Naturally, she's fully confident that the Sheldon Family would verify her as their granddaughter.
Because the bloodstain and hair samples in her possession are actually Charlotte Allison's.
Charlotte had guessed this as early as yesterday when Ms Shirley accidentally cut her finger. The moment Ms Shirley nervously treated her wound, she realized it was Hazel Allison's second plan, collecting not just her hair but also her blood samples, making it more convincing.
Hazel has Charlotte's samples, so she could easily swap them with her own, bearing the original test results.
