S3 Ep4 - Tumblr Posts

ok so I'm pretty certain this has been brought up by many people since the release of s3 but how do Klaus's powers actually work? Do people turn to ghosts immediately after they die or is there some kind of process? Because if they become ghosts straight away wouldn't he have seen Jayme and Alphonso's ghosts after they die in ep3? On the other hand, if the dead only become ghosts when they have unfinished business, that still doesn't explain why the two don't haunt Klaus or the other Umbrellas.

I feel like they wouldn't be the type to get over getting brutally murdered by some randos that broke into their house and would take any opportunity to terrorise them. I get that the Sparrows are supposed to not really be a family so /maybe/ they didn't think their siblings would care that they died but we can literally see both Fei and Sloane get super upset that their siblings got murdered so they can't have not known how much the others care right?

I get why the writers didn't add ghost Jayme and Alphonso to Klaus's already very packed s3 storyline but I feel like some kind of explanation would've been nice. Maybe they could've tied it tp something to do with the Kugelblitz (is that how you spell it 😭)?
