The princess ran to her long lost twin-sister crying, taking her in a bear-hug while an unending stream of Râkshasan words flew out of her mouth. While neither Aditi, Undine nor Colin understood any of it, but the tone was both full of the joy of being reunited with her long lost sister, and the grief of being separated for so long.
Once Rabhya calmed down, she said "While I’m happy to finally meet my sister and see she is well, I’m not sure it’s a good thing." Before anyone could ask, she explained "Now that I know about Aditi, so does my bodyguards, and some double as spies for the Râkshasan nobility, who will exigent to meet the two of you. I can temporise things so you only have to come to my country during the next holidays, but it, alas, doesn't change the fact that learning Râkshasan became necessary for your survival, and for any other slaves you might have."
Princess Rabhya took all her free time helping her three students learn the two forms of the Râkshasan language. Because 'true' Râkshasan needed both a sens of hearing as good as a cat’s, and vocal cords able to produce the full range of sounds of a Râkshasa, causing the creation of a 'simplified' form for commercial exchange.
Naturally, all three of them were taught the simplified form, since two of you could only speak that form. But Rabhya also made sure Aditi would know the more complex form of it, knowing the noble would try to use it to mock Colin and her sister. She also used the fact Aditi was, technically, Colin’s magically bound slave, with all that imply, to make sure he could understand 'true' Râkshasan as long as he listened to it through his girlfriend’s hears.
At long last, the time to visit the Râkshasan homeland. (Colin had warned his parents of the situation via letter.)
What will happen to Colin, his 2 slaves, and their new friend in the country of Râksha?
