first of all …
there are 2 "the one"s 
sannie’s version: "The One" :: Cannabis Sorten Infos
and the original: "Blue Orca" :: Cannabis Sorten Infos
(both unrelated …
i don’t think sannie even knew that the earlier one excisted.)
anyhoo:
sannie kind-of “simplified” the whole “sannie meets mota”-episode
and created a bit of confusion that was never officially cleared up.
__
what sannie calls “blueberry indica” and “the one” are in fact
phenos he found in the “toxic blue”-seedline from motarebel.
(Sannie “simplifying” the lineage of motarebel’s “Toxic Blue” to
“Blueberry Sativa” x Killa Queen / NYCD, didn’t help things, lol.)
so…
Blueberry Heaven =
“Blueberry Indica” X “The One” = Toxic Blue “F2” (but in fem version)

i hope this helps a tiny bit …
the information is still out there in detail on the opengrow-board:
