And before the cases of episode 50 & 55 Galar episodes were always back to back. Yet episode 50 & 55 broke this trend as even though they took place in Galar they were separated.
Similarly two of the episodes that that had two segment thing going on would happen right before Ash and Goh would go to Galar in the following episode and yet in the case of episode 58 the episode following it did not take place in Galar.
So no just because we haven’t had a case of Ash having two episodes back-to-back in Pokémon Journeys doesn’t mean we couldn’t get one, especially when this series has been pretty unpredictable.
While its a possibility, i still think its unlikely. Ash's focus episodes are sparse as is, but here is the thing: Every time Ash gets a focus episode, Goh either gets a focus episode right before it or the episode following it or the second episode after.
JN05?JN06: Goh focused (Goh catches Scorbunny and the Bugs)
JN07: Ash focused
JN08: Goh focused (Iceberg race with Mantyke in a role)
JN10: Shared focused, despite Ash catching Dragonite, but Goh takes around 5 minutes to catch Dewgong.
JN012/JN:013: Ash focused (Sets up his goal)
JN014: Goh focused (Goh gets Golurk)
JN015: Goh focused
JN16: Ash focused (Ash gets Gengar)
JN17: Goh focused (Scorbunny evolves)
JN18: Ash focused (PWC battle against Visquez)
JN21: Ash focused
JN22: Goh focused
JN25: Korrina battle, shared focus.
JN27: Ash focused (Ash catches Galarfetch'd)
JN28: Goh focused (Goh catches Sobble)
JN33: Goh focused (The Bug lady)
JN34: While you can class this as Ash focused (Bea 1), its more shared than Ash focused imo.
JN35: Goh focused (He catches a Pikachu)
JN38: Goh focused (Aerodactyl)
JN39: Ash focused (Bea 2)
JN40: Goh focused (Flygon)
JN50: Shared (Dracovish and Arctozolt)
JN52: Ash focused (Rinto1)
JN52: Goh (Gets Diglett and Dugtrio, so its more Goh focused than anything else, especially since Goh gets character progress with him realizing the Diglett need his Dugtrio more and as such releases it)
JN56: Supposed to be Ash focused, but is shared, since Goh has a major role in the episode and gets an evolution to boot
JN59: Goh focused (Grookey)
JN60: Ash (Rinto2)
JN62: Goh (Sobble evolves most likely)
JN63: Either Ash or shared (Dracovish gets focus)
So this makes Absol being a Goh focused episode extremely more likely than it being an Ash episode, since Ash has never gotten 2 episodes back-to-back (If JN63 is Ash, that would make it 3 episodes back-to-back with JN63, JN64 and JN65 being Ash's and i just can't see that happening), while Goh does get multiple focus episodes back-to-back.
