Snape’s Patronus/ Harry’s Eyes

I think "I've got it!"  Course I have said this before, and well
 we 
will say no more.  But here it is:

Theory 1: Snape's patronus is something to do with Lily.  That is 
why it "would give too much away" as JKR said.  It is also why DD 
trust Snape. Because Snape's patronus gives away his real 
allegiance. 

Theory 2. Snape's patronus is something to do with Harry. All rest 
above applies here as well.  

Now I hear you all saying, `but everyone that saw it would know'.  
But do we know of any time when someone has seen it?  If someone 
does remember a time, please remind me.

Harry's Eyes
As I was listening to HBP on CD something jumped out at me when DD 
and Harry were in the cave. (no, not an Inferni) 
The reader said that Harry looked into DD's blue eyes that took on 
the color green from the reflection of the liquid in the pensive.   
It just sort of hit me
  green
  Lily
 DD
 Harry.  Is there anyone 
else in the series with green eyes??  Anyone?? I don't remember.  
But if there isn't, what if the color green for eyes is a symbol 
(ya, you knew I was going to throw one in here somewhere)..  a 
symbol of sacrifice.   If this hunch is correct, it doesn't look 
good for Harry, but then it never has, so nothing new there.  What 
do you all think?  Green eyes = you are going to give your life for 
another or the world.
