Keene, unlike Pobble's amphetamine augmentations, has a nice mixed booze and Valium flow to him; which is to say he /seems/ normal unless you start dealing with reflexes. Of course, he's so accustomed to operating like this that he hardly seems impaired. He walks nice and slow back towards the gardens, even as Millia zips right by him, to be sure that Pobble doesn't get out of arm's reach.
