Snape as a Death Eater/ Magical Fireplaces

Hi I am new at posting but have been lurking for a while. Some 
thoughts I had were:

In GoF while talking in the Graveyard about missing members Voldie 
tells the DEs "One, who I believe has left me forever...he will be 
killed of course...and one, who remains my most faithful servant, and 
has already entered my service." So the one who has left forever 
maybe this isnt Snape. The obvious choice for the one that is his 
most faithful servant would be Crouch but what if it were Snape? And 
if Snape really is still a DE. I know, well then why hasn't he killed 
Harry already then? I don't know. Just a thought. 

About the room with secret magical powers, maybe it's the kitchen. 
The fire place could be hooked up to the Hogwarts floo network. The 
house elves might use this system to travel around Hogwarts and the 
house common rooms to clean and such without being seen. Maybe Dobby 
can help Harry access secret and off-limit rooms this way. 

Be easy on me please.
