When Cole called to them, Momoko and Saru entered ignoring Crane. After he asked, Momoko answered "Cole-san…I, well we, heard about Sarah-chan," When he asked as to how he can help, Saru sniffed once before he asked "I was hoping…that I could see her? She's my girlfriend…" After Saru would get his answer, Momoko spoke up, "There's also something I want to ask. I want to help with the investigation of this Fairy Dust case," She knew that whoever was responsible for the Fairy Dust, was also responsible for what happened to Sarah. She wanted to help her friend in every way she could, including making the responsible party pay for what they did.
