Thank you! Really interesting story! Interesting, Snape using his Patronus to justify his feelings for Harry, like a kind of sounding board. Also that he uses it to assuage his guilt by using it for its original use as a messenger, but in this case the messages are for Lily - though he knows she can't receive them. Glad my prompt was okay for you!
Thanks again for the lovely gift! Hope you have a merry snarry! :)
