Almost like Arthur left aome of it for inquiring minds to dabble in when he visited the 14th. Maybe he is planning on using anyone foolish enough to try to learn the shadow ability as his own personal teleporter. He clearly removed things from the castle and training room, leaving enough to be useful but not a threat, maybe?
It would be a nice twist if instead of Bryce being the plotter, Quinn could plot to have Bryce dancing in his palm this time. I believe he can only use/take the shadow of others if they want to help him. But heck, just imagining Quinn knowing about Bryce breaking into the 14th, but letting it happen, and then turning the tables by using the shadows of his own soldiers against him would be great. In a, 'this time I was the one pullung the strings'. Not gonna happen, but would be great. Id like to see Quinn use his past experiances to his advantage and know that Bryce is plotting, instead of getting caught in another trap. Looking forward to where this all leads! (also.... Bryce... do you have no clue that if you create shadow users Arthur can find, and warp, directly to you?)
Boo stop making martial arts Quinn's weakness when he was pretty good with it at first. More so you brought the same thing up during the Blade arc and solved it with Quinn training with Borden only to bring it up again. If Quinn is going to martial arts training can you have him figure out how to do a double hammer strike and kick would be nice for his talent in that area to get shown off. I would rather you make it due to lack of proper teachers and time rather then talent issue if you are going to go down this route.
