Some questions

[snow15145]

Just a few questions I've been pondering
and since there hasn't been 
much activity lately I thought it might be a good time to ask. 

(1) Did Marvolo see his daughter as a squib because she lacked the 
ability to speak parceltongue? Is parcelmouth a magic ability for 
anyone magical or an inherited trait only representative of the 
Slytherin bloodline? 

(2) If the castle is protected from anyone flying into the grounds 
(via Dumbledore and Harry flying into Hogwarts for the final showdown 
on the tower), how did the Ford Anglia manage to get through the 
magical defenses in COS?

(3) If the Phoenix has healing powers in its tears, why didn't Fawkes 
just cry on Dumbledore's wand hand that was burned by the Horcrux to 
heal it? 

(4) Why was the Bloody Baron hanging around the Astronomy tower (like 
a lookout?) the night Harry got the Slughorn memory? Whose side is 
the Baron on, is he one of the ghosts who was interested in Harry 
being the Chosen One that Nick refused to comment on in the chapter 
Snape Victorious? 

(5) How would the twins even know about the `unbreakable vow' at age 
nine let alone attempt to perform it on a five-year-old Ron?  Where 
did they see someone doing this at age nine that they would even know 
of `its' existence? 

(6) Does anyone else see the big blonde death eater as a giant with 
less skill with his wand than even Hagrid? Is that why the blonde 
death eater chose to ignite Hagrid's cabin because he realized it 
would be futile to engage stunners against a giant, being one 
himself?  

If any of these questions have been asked before and I missed them or 
they were discussed on TOL while I was on hiatus, please except my 
apologies.
