^ Silence and Saria have very particular dialogues about each other (and Ifrit) to imply that they have a past together. It's fan-fantasy to say they're legitimately divorced, but their relationship seems like that of a broken family
^^that's some Waterworld nonsense yo. Fo' reals, the only even remotely logical and plausible place for the things is the sides of the neck for the same reasons real vertebrates have them there too. (Putting aside the fact that there's no way to meet the oxygen requirements of anything like human physique and metabolism with the surface area available there...)
@FluffyCow Its semi joking and semi serious. Ever since that MariShion off-collab where something allegedly happened between them, Shion has been avoiding the topic like the plague and has denied multiple times something happened, while Marine in the other hand has been vehemently trying to make Shion admit that something did happened that night. Whether she is or not trying to destroy that ship is just me merely speculating from the fact that they've barely collabed ever since that.
^I suppose the nose would make a good point of comparison - the protective outer covering is no more sensitive than any skin, while the inside is all mucous membranes and whatnot and quite sensitive indeed. ('Course the very function of gills involves constant passage of water plus whatever particulate matters now may happen be floating in it through them so high tactile sensitivity there would be pretty counterproductive and distracting...) Sticking your finger in there is not generally considered a terribly erotic experience tho, and in the configuration depicted here they'd be opening directly into her lungs which sounds all kinds of y a b a i to me...
