Theory:Doctor Who television discontinuity and plot holes/The Wedding of River Song

Because the doctor was inside the Teselecta, he described it like wearing a suit, and it was shown when he grabbed rivers arm, that the restoration works through clothing, so the same princible applies here. The Teselecta is a shapeshifting robot, it could easily mimic the appearance of the start of a regeneration.

 * How did the Teselecta start a regeneration process when receiving the initial shoot ?
