So, plot progression WMG:
1. Chiyo, rejected by her mom, decides to voluntarily join her kidnappers (look at me, mom!)
2. Sakura busts asses getting her daughter back, is rebuffed by said daughter
3. After some drama and proper happy talk, they reconcile.
Or mangaka-san can make Chiyo into some sort of recurring nemesis for Rokudou, specially if the kidnappers can show her that she was fundamentally brainwashed by Rokudou's mark.
