All well and good, but what is the point of all of this? How does it further the story?
Every possible bit on emotional torture for Harry is furthering the story :3
Well Mirror Mirror Murphy is actually a valkyrie and can stay at Harry’s side until the end
Let's be realistic. Mirror!Murphy would hate Dresden's guts and then probably will be killed by Darth Dresden.
Not to mention is extremely doubtful she would leave her own dimension unless dunno - it's destroyed by Outsiders in finale of MM.
She is not inlove of his Harry, she probably is not her friend either, but her character is the same. So when she sees our Harry she will react more or less like our Murphy would. And Harry would have a lovely memory of her for ever.
I don't know why we assume it's gonna be lovely on his side.
"Because we don't like that Murph is dead" is literally the main reason for everyone saying she needs to come back from Mirror Mirror/Gard was wrong and she can show up as a Valkyrie/Whatever other third reason.
Which, fair enough, there are characters I'd like to see again (in both this and other series). But realistically speaking most of the time characters are killed it's because their part in the narrative is done.
So no, there's no real furtherance in the story in bringing Murphy back. But yeah, people will miss her and want her to return.
Putting Murphy in Valhalla is IMHO perfect Chekhov's Gun showing it's not done.
I mean for all I know it can mean she's gonna be killed 4ever second time.
And we may see non powered up warrior princess Murphy in the BAT when the rules are thrown out the window, but by then the Murphy we knew is long gone. She may not even have her memory anymore
If Murphy shall return as Einherjar in BAT, I doubt she will not be herself. Primo it will be at most 10 years then. Secundo Valhalla unlike Hades is all about memory. Throwing Murphy into oblivion would be totally against it's basic principles - that deeds of people of valor shall be remembered.
If Murphy is like full Murphy soul and stuff and not just shade inhabiting body - which is option after all Odin is not source of souls, and WOJ states clearly all souls finally shall return to it's source no matter what would happen to them in meantime - but if she has her soul, she will be herself.
