Kasa is Anabel's grandmother, both are different in personality one being soft spoken and introverted until battle whilst the other one dabbles in theatrics , due to being able to disguise herself, personality wise Kasa is probably still swingy even in old age if her spiffy style is anything to go by.
The mystery of Suicune and the Unown in the Crystal intro makes sense retrospectively if you assume that all 3 legendary beasts represents one of their "parents", Entei being the leader who is associated with Ho-Oh due to the latter bringing the 3 back to life, Suicune with the Unown as being a "messenger" of the north winds whilst purifying the universe in cosmic realignment (to its own degree, mostly purifying lakes) and Raikou being assosiated with Arceus, a Divine force which fits in with it being Lightening, making it some sort of intricate circle of life.
The Unown making signals in the intro was actually trying to resonate as the Azure flute, it was possible that they were trying to call out to Arceus, or perhaps try to affect the world....but they got abused after Team Rocket (indirectly) tried to alter the universe with the evolution signal.
The BW protagonists has a slight fetish towards spandex, they justify their diving suits (that they wear under their clothes) due to making it easier to explore more places to swerve off any suspicion.
Fantina and Glacia is from Kalos, they're both from far off regions, whilst Glacia was stated to come from a "cold region" whilst Fantina went to a region with slightly-colder-than-Hoenn temperatures, for Fantina it works both ways in dubbing being French in English language versions of DPPla aligns with Kalos fantasy counterpart culture with France, whilst her Japanese side is Russian...Kalos could be pretty cold due to the 3 different climates and Russia would be cold.
cont. later perhaps.
