Hmm..a little brainstorming of my own...
Wall in the shower...hit by the fire(ball, bolt or some kind of other fire attack or heavy weapon (well no further damage? Just the fridge)? What was the atackers position?)
Is it possible that someone tried to extinguish fire on something/someone using the shower for this purpose?
Fridge - possible cover? Again - position of the atacker? Defender? Doors used as an improvised cover?
Milk...how long it is spilled? IMO when this all happens? If U dont know exactly, take some samples, Ill make anylysis in my chemistry lab. In fact...take any samples you thnk are interesting or important, Ill run analysis for all of them...
That part about drone I didnt understand well, my english...what is "busy body drone"? And about that camera...does it mean that there are sparks still, or that sparks ignited something...or sparks ignite is the phrase that says that there are ocasional electric sparks (really srry:)
Char means ash?
Is it possible to recognize what was the menu from remains on the dishes?
That candle...IDN...
Broken glass from the Balcony: does it mean external balcony or internal balcony on the top of that glass stairway to the bedroom?
Where the fire begins?Alarms off, CHN down...no, this doesnt look like an accident, even if the victim is Kiku father who was suffering from illnesses of the high age and such people may be dangerous to themselves...but we still dont know whom the body belongs to...
Does the water came from rain? Or were there really two materialized spirits engaged in the combat? (very low level of other damage, furniture is just wet, not torn apart...??)
Does that robot have a memory?
