[spoilers] why didn’t Floki tell anyone about the slaughter of the farm settlement in Wessex

Im so confused. A farmer escapes the slaughter and informs Ragnar about the events at the farm settlement (with Floki present)

Why didn’t Floki tell anyone about this? He was already falling out with Ragnar, then he was chained to a post in public for the killing of Athelstan, then he was chained up in a cave. And eventually set free.
