The Nike special branch has caught up with him. The men in black wearing special nike black runners that give each wearer the power of ten men, using technology and pharmaceutical implants rumored to be have been gained from the infamous area 51. They snuck in under the cover of darkness, drugged him and whisked him away.
This very moment he is under sedation following an operation involving planting a special roaming chip placed behind the right ear. He will no doubt be released again. He will awake one morning at home unaware of what occurred.
People like Dr.H who have been snapped up by the likes of Nike special branch can only be told apart from the regular civilian by a small bar code tattoo on the back of their neck just under the hairline.
or perhaps he forgot to pay his internet bill
