Just picked up the latest issue of Corocoro Ichiban, which continues the Nacrene Museum plot.
Upon Black's arrival, the six Gymleaders are already battling the Dark Trinity, and their combo strategy seem to be working quite well. Lenora wants Black to take care of the Grunts inside the Museum while they hold down the Trinity, and thus Black goes in, where the Grunts (the three same girls who stole the skeleton before) are leading others to search for the Dark Stone.
Back outside, the Trinity are barely fazed by the Gymleaders, and they split up to deal with the Gymleaders in a 1 vs 2 fashion (kinda reminds me of the battle between Team Galaxy vs Gymleaders battle at Spear Pillar). Anyway, Brycen seems to be the only one who could stay completely calm and unharmed while the other 5 get progressively worn out. Brycen faces the red masked Trinity member who uses Larvesta against his Cryogonal, but despite the type disadvantage, Cryogonal freezes the vapour in the air to ambush Larvesta with an ice chain. The green and blue masked Trinity guys combined their attacks to smash down Cryogonal, but as it vaporizes more, it creates an even bigger ice chain, finally seizing and trapping all three Trinity members and their Pokemon. However, the Trinity guys are still unfazed, as they remark that they come fully prepared. At the moment, the sky suddenly turns dark.
Inside the Museum, Black has taken out all the Team Galactic Grunts. He hears a giant rumbling coming from the outside, and gets out to join the Gymleaders. To his shock, Thundurus, Tornadus and Landorus have appeared, and with their combined powers, are hurling and throwing the 6 Gymleaders around with a powerful gale and landslide. The Gymleaders are horrified that Team Plasma has gotten their hands on the three legendary Pokemon, and Clay tries to stop Black from coming near, telling him that although he has proven his strength, he is still just an ordinary trainer and there are somethings that he cannot achieve.
Black seems irritated by that comment and starts to charge forward. His Pignite rams into Landorus but the genie seizes it by the neck. The Dark Trinity frees themselves from the cie chain, and laughs that the table has turned. Black gets increasing infuriated, and his fury in turns affects his Pignite to evolve into an Emboar, breaking free from the grasp of Landorus.
Meanwhile, N has arrived at the Dragonspiral Tower with Gigi. He looks up and muses that the top floor of the tower is where Truth and Ideals meet.
As I guessed, the three genies are the aces up Team Plasma's sleeves. So this means White's encounter with Shauntel takes place some time when Black was in Driftveil, probably between the chapters of Zorua on the bridge and Black meeting Cheren?
Gigi is still a Tepig by the way. Oh, and the reason I use the colours to depict the Dark Trinity is because the 'pattern sheets' used on their masks are exactly identical to those used for the elemental monkey's colours, and those of the Striaton brothers' hair colours. I haven't seen a full coloured pic of them to verify this, but I think the hints are obvious enough.
Oh, and according to the twitter of (I forgot Hidenori or Yamamoto), the next issue of Pokemon Fan is coming out 3 March. Hope they'll show us what's up with White next.
