Birds of a Feather: Voyage No. 1
An astonishing number of Potterfans — unless you mostly hang out with Snape fans. Then you won’t be astonished at all — are firmly of the opinion that Severus Snape got a very raw deal from his creator.
Considering that by the conclusion of the story arc the whole universe seemed willing to warp around Harry Potter in order to hand him the answers to questions that it never occurred to him to ask until it was practically too late, and to ensure that he would just happen to be in just the right place at just the right time, with just the right piece of information to fulfill Albus’s master plan, it's hard to disagree.
Especially when — as early as Book 2 — that universe declared that Harry Potter would be spared from death solely because of his loyalty to Albus Dumbledore, while Severus Snape — who was loyal to Albus to the very end, just… wasn’t.
It really doesn’t seem very fair, does it?
It lacks consistency. It lacks symmetry. It smacks of favoritism.
Well, that’s the thing about creating characters, and putting them in stories, and turning them loose for the world to read. Sometimes they get away from you and go off and have adventures of their own.
Given his response to Harry’s encounter with a basilisk, It’s safe to conclude that Fawkes might have had something to say about going off and leaving Headmaster Snape to die alone in the Shrieking Shack. He wouldn't stand for that for a moment.
True, he does miss his Albus. But Albus is gone now, and he thinks it’s time he adopted another wizard.
Fawkes doesn't understand why more phoenixes don't adopt wizards. Wizards can be so entertaining.
