Aranese is fairly normal Gascon speech, I don't think it qualifies as its own subdialect [1]. This being said, there's something to be said about Gascon as a whole potentially being its own language, as is considered Catalan. Among Occitan dialects, it's highly eccentric.
As for Aranese speakers, to me (I have some amount of Limousin and Provençal) native ones [2] are understandable to the same extent as other Gascon speakers, but new speakers who bring Castellan phonological features are incomprehensible. If it manages to survives in this environment, it could truly be a new language in the making.
