To quote the sixth Doctor :
In all my travelling throughout the universe, I have battled against evil, against power-mad conspirators. I should have stayed here. The oldest civilisation: decadent, degenerate, and rotten to the core. Power-mad conspirators, Daleks, Sontarans, Cybermen - they're still in the nursery compared to us. Ten million years of absolute power. That's what it takes to be really corrupt.
Is it any wonder McCoy became so Secretive and Manipulative?
For any "NuWho Only Fans", the Classic Tom Baker Serial, Genesis of The Daleks,
where the Doctor is forced into a situation where The Time Lords want The Doctor to destroy the Daleks at their Genesis. This Story, is said by Many an Uber-Fan, to be the "First Strike in the Time War". I think all "NuWho UberFans" should see this for Reference's sake (IMHO, Of course)
One Day I hope to be the Man my Cat thinks I am
Where are we going? And why are we in this Handbasket?
