In the beginning of OotP, a cracking noise reminds Harry of the sound 
that Dobby made whenever he disappeared.  That made me realize that 
Dobby did in fact apparate and disapparate INSIDE Hogwarts (when 
Harry is in the infirmary)in CoS--which everyone says is not 
possible. Does this mean that Dobby has deeper powers that we have 
thought?  I dunno. 


Now Key of Kenney:

Yeah, it seems this kind of chatter has been previously discussed, 
however with little to no interest. whenever i bring it up, no one 
replies... anyhew, i think it lends a hand to house elves being 
underestimated as kreacher was in OoP...

they (in my oppinion) will lend a hand to the destruction of you know 
who.

from the Key Of Kenney
who is utterly dissapointed at the lack of nancy drew-ness in OoP...
