So not Maori.
Even Q's bigger tat was Polynesian more-so than Maori.
Chakotay's tat was alien. Nothing to do with earthling bollocks.
B'Elanna flatlined to talk to her mother on the Barge of the Dead.
"Death" itself told Janeway that it was coming for her in Coda.
Tuvok can telepathically suck up consciousnesses and then dump them into no where special in particular.
Seven should have been able to talk to her parents when they were all part of the collective... At least one of them should have the genetic defect that allowed her to "visit" Unimatrix Zero... Unless Magnus was cuckolded? Which hardly makes sense if they tracked her DNA to Admiral Hansen.
Kim died and might want to pray to himself.
Sam must have been fucked up about her daughter still walking around after dying during birth.
Kes was dead in a coffin in a cargo bay after the second month of season one, which was effectively a grave that the other crewmen, and Kes herself must have visited and talked to reverently for years after Janeway murdered the little girl, especially after Kes turned into a god.
If Chakotay wanted to talk to his ancestors, he was a 15 minute shuttle ride away from a couple of them in Futures end, so "her" hauting spirit in the future might have felt snubbed.
The crew could send timedelayed email to Braxton calling him an asshole.
Chakotay did share his peyote machine with others, introducing them to their animal spirit guides inside a hive mind he maintained. B'Elanna killed her guide... I wonder why she didn't meet herself on that Barge because of what happened in Faces?
I wonder if anyone tried to use MulCahey as a substitute for One?
Did Quicksilver B'Elanna who died before she knew she was Quicklsilver go to the Barge?
Did Tuvok miss his sentient Syphilis enough to get a medium to contact it in heaven?
Stuff.
