Earlier, Pythia has regretted visiting Dr. Kiba part of the timeline. She thought the earlier two scenes she showed to Kiba were far too grim so she should show him happy times. After all, she has basically robbed him by taking 5 jars of Spatial Golden Sand - a rare and mystic commodity that was almost priceless on Earth.
As such, she believed he deserved to know his future past not limited to serious events. So with great efforts, she used her precognition ability to sense one of the times where he was truly happy and carefree.
Alas, it was far too late when she realized his meaning of happiness was different from the worlds. What's more, Dr. Kiba's way of treating his patients was something she has never seen or heard before. She was shellshocked by the examination procedure and stunned beyond words when Dr. Kiba used his instrument for treatment.
