Forum:The Key 2 Time in titles

Does 'The Key 2 Time' need to be in the titles for The Key 2 Time - The Judgement of Isskar, The Key 2 Time - The Judgement of Isskar, The Key 2 Time - The Chaos Pool?

And, if so, why isn't it in the title for The Prisoner's Dilemma?

Isn't 'The Key 2 Time' just an over-arching title/arc for the stories? --Tangerineduel / talk 15:59, August 30, 2011 (UTC)
