Vampire souls are tied to their bodies, so you can drink them up with blood and thus commit diablerie.
Just got that random thought by chance, so wonted to be sure are we free from Louis or can he come back to cause trouble.
--->Is soul of Louis utterly destroyed to keep Cattleya "alive"? Like food we eat being broken into smaller blocks to build and fuel a body.
No matter how much blood you pour on his ashes, even if his body was whole, or divine intervention was attempted... he stays dead. Forever. There is nothing to bring back. (and hopping for this).
--->If it was as Alucard... souls of peoples he ate were still whole, like maybe stored in some battery of sort. Souls could be destroyed/sacrificed by Alucard to prevent his death or summoned as creatures to fight. Alucard was also having problem when eating soul with wrong kind of ability, as he couldn't distinguish self from other souls he held or something like that.
If this idea proves right, then maybe in theory, Louise could be revived if Cattleya is killed and then necromancer/demon gets his hands on Louis's soul out of land of dead. Or Louis has enough willpower to try make voices in Cattleyas minds, trying to take over her body, or something else to get free.
In both cases, soul of Louis would not be tied to his body/ashes any more, so pouring blood on ashes will not help to bring him back.
Human souls just depart after death under normal circumstances, so vampires can't drink them unless they first turn the victim into a vampire.
Not sure on that. Might be more like vampire always eating souls or parts of them, as vampire seemingly eat life-force, I think that was mentioned? Minions were double-dead if eaten by vampire, blues can't do anything? Vampires get permanently killed if eaten by vampire,
because vampires eat life-force?
So I guess one of those not normal circumstances is for human to be killed by vampire who drank all blood...
Hmm do vampires need blood as medium to feed or could they eat ghosts (probably not very nutritious as souls of alive humans).
That might give some help to Louise as in games, minions had problem with magic and water, like small fairies that charmed them with magic and led into water to drown... except blues who are too stupid or resistant to mind altering magic... or both. And use magic to resurrect minions, along with magic attack as their hands are glowing when striking, as manual of game says that they can hurt ethereal enemies.
Though there are also reds manipulating fire, along with greens being invisible and ignored no matter how much they stink. Cattleya might be used similar to minions for dealing with some magical threats if Louse is in need of shield between self and enemy.... Can Cattleya use magic, beside vampire kind like hypnotic gaze?
Cattleya and blues could be best answer to defeating ghosts and spirits, as one example, if any is met? Doubt that setting them on fire, "clubbing to death", zapping with lighting or drowning in acid will be of much use... Henrietta might also work by binding them under her control, but it's not like Louise is happy with necromancy.

Best abandon this train of discussion? A random thought that went too far?
