It's About Motive

BG's thoughts:

1. Why did Snape kill DD?
>Snape told DD about the UV

>Snape knows DD is dying from whatever "killed" his hand with only 
Snape's potion or a spell keeping him alive long enough to prepare 
Harry to go on without him

>Under the circumstances at the Tower Snape cannot give DD the 
potion and he must save Draco's soul and live himself to keep 
working for the Order.  He must do what is right.  He must keep his 
word to DD to do whatever he is asked.  DD asks not pleads with 
Snape to kill him or possibly release the spell that is keeping him 
alive.

2. Why did DD trust Snape?
>Snape hid Baby Harry for DD until DD could make the arrangements at 
the Dursleys.  Hagrid picked up Harry and took him to Snape at 
Spinner's End - that is why Hagrid trusts Snape. 

3. Why did LV kill James but said that Lily did not have to die?
>LV had made an UV with Snape as a reward for telling about the 
prophecy.  Lily alive or dead made no difference to LV so it was an 
easy bargain for him.  So Lily did not have to die but she got in 
the way when LV was desperate to kill Baby Harry and in anger he 
forgot the UV and killed Lily.  Breaking the UV and the rebounded AK 
are what destroyed LV's body - the AK does not destroy the body so 
something more must have happened.

4. Why did DD say to Petunia, "Remember my last"?
>My last what?  Visit?  Letter?  Possibly DD made an UV with Petunia 
that he would protect them if she vowed to keep Harry until his 17th 
birthday.  Maybe it was a double vow.  DD protect her family and 
Petunia to give Harry a home.

I'll add to this that Petunia will be the one who will show magical 
abilities late in life.  JKR said ".....there is a character who 
does manage in desperate circumstances to do magic quite late in 
life, but that is very rare in the world I am writing about.  The 
key phrase here is "desperate circumstances".  Is she magical or did 
DD give her powers to defend her family if she gave Harry a home to 
complete Lily's charm until he comes of age?
