To be more specific, I am talking about when Nagito was telling Hajime that he has no talent and was basically harrassing him verbally any chance he got in the fourth case, and yes, what you said about the Reserve Course. Also the fact that Nagito was being a jerk in the third case as well (was it the third?). It was a great arc nonetheless.
To be honest, I am just glad that everyone in DR2 is alive, besides you know, Chiaki. I remember crying my eyes out when Tanaka was executed (he is my favourite, so you can probably see why) along with Chiaki's and Peko's execution.
Honestly, the Danganronpa games really want to kill off the ones that I considered my favourites, unlike Ace Attorney. (Well, there are some cases that AA did kill some of my favourites along the way). :c
Yes, the game of DGS2 did start out with Susato in the beginning, being called Ryutarou Naruhodou since Japanese females aren't allowed in the courtroom profession, as said in the game. In fact, I think she did become an attorney due to Kazuma Asougi and Ryuunosuke Naruhodou, and she does actually think of the two of them a lot, even acting as them too. c:
