An ogre, quite to its reluctance, is so fastidious in terms of the approach of its welfare.
At night, one ogre, perceiving the fluctuations of animosity in its body, will summon the other head's attention, thereby creating a flux of attention throughout its body signaling the other head to wake up from sleep and thereby, with politeness create a unity whereby the ogre isn't upright with one head still adrift in a deep sleep. A further note is that the ogre is so able to bring mischief to the other head, they are in a constant battle for prowess to survive not from the battle one army against the next, but one head's complete control and dominion of the body against the other head's dominion, whereby one head's consent can take a sword and cut off the other head, or punch the other head out thereby creating one head that is incapacitated or completely killed, or beheaded from the construct of the ogre's physique/body.
