That's pretty nice, I didn't know the first one, also either Ciel or Samson dies depending on the ruby ring. I figured some other differences on my own too, Anna's dialogue when we wake her up is the most optimistic during the Zekrom route, in the Reshiram route however, depending if you defeated Solaris or not, she acts differently. If you defeated Solaris, she would be a bit nervous and mentions a broken wing boy but still be determined to fix things. If we didn't defeat Solaris, Anna would basically have a panic attack and apologize to the PC.
Also the extra dialogue with Radomus is probably because of the Zekrom or Reshiram route. In the latter route, his backstory would be more fleshed out, where he mentions the merchant he alluded before was himself(he foreshadows himself, what a egoistical madlad) that stole the keys and turned them into Jewelries. The Emerald Brioche he gave to the Jeweler(my theory is that this Jeweler's daughter was Luna, and Elias erased her memories), the Ruby ring to Corey, the Sapphire Bracelets to Monty and Caroline(both of them gym leaders), and kept the Amethyst Pendant for himself and his wife. Also Nostra, the Jirachi, probably belonged to Anna's mother as well.
