What do you think really happened?
Like I stated, the attack did occur but the cub being a cub should have scampered off once it realized that it was not match for its foe. Could be that the cub was orphaned and starving or was rabid which might explain why it didn’t break off the attack. Too many questions and not enough answers to definitively come to a solid conclusion. Only the runner knows the full story and with this being a young cub he’s probably going to stick to the narrative that doesn’t make him look bad. Cheers!
