DE Spy in Hogwarts: Bloody Baron (new theory)

[Hagrid]

No: HPFGUIDX 137513

What do we know about the Bloody Baron?

He was "... groaning and clanking up on the Astronomy Tower, it's a 
favourite pastime ..." where the Death Mark was positioned.

He saw DD arriving, and may have kept a check on DD's movements.

ok, so that is very circumstancial ... but what do we know about him?

- Slytherin house ghost 
So he is familiar with almost every DE. 

- He is called a Baron (a royal term) when there are no Princes in 
WW.
This suggests he pre-dated modern WW political structure. 

- Feared and avoided by other Hogwarts ghosts.
So he enjoys as much secrecy and privacy as he wants

- He is Bloody.
Binns (COS ch9) said, "... it was an age when magic was feared by 
common people, and witches and wizards suffered much persecution." 
when talking about the founding of Hogwarts and the story behind 
Salazar's Chamber itself.
Being bloody, the Baron may have been one of the victoms from around 
that time. 
And favouring Slytherin house, it would not surprise me if he was a 
relative of Slytherin himself !

Missing information about him:-

We see Sir Nichollas talking to his house students, but haven't 
heard dialogues between the Baron and Draco (which were not done if 
front of Harry anyway)

Is the Baron a Parselmouth?

??????????
Moaning Myrtle is the only ghost that has taken an active role in 
the developement of storylines so far. 
Nearly Headless Nick has talked a lot but said nothing of grand 
importance.

If any ghost takes a major role in books 7, I'd keep an eye out for 
the Bloody Baron
