I haven't checked out version 1.2.2 yet, but I've played version 1.2.1. Here's the thing:
After you start the Truth Expansion (I mean, Epilogue Act 1), check the Fortune Teller to see if she mentions Rinie. If yes, visit the camp, enter the tent with the bed. It should have the New Quest indicator on the bed. Use it to start the new quest and return to Bellia. Bellia will be accessible after this point.
