Wikia HT - Hollis' final moments

A man who clearly missed his calling, since he show all the classic symptoms of 'going postal', Hollis (no other name given) has a lethal grudge against Ken Lydecker and the explosives and shotgun to do something about it. Unfortunately, for him, he doesn't have the brains, allowing his true target to slip out with the rest of his released hostages, and leaving him alone with Christopher Chance, who proceeds to resolve the situation with a less-than-controlled detonation. Since Hollis is wearing the large quantity of explosives at the time, his demise, while technically speculative, does seem like a safe bet.

He is the series first 'bad guy', although massively misguided might be nearer the mark.

Hollis is played (briefly) by Mark Moses.
