I chose to let Vast turn Beth and I stuck to the more aloof answers in their dialogue and picked choices that said there was nothing left for Beth in her current life so she might as well try a different kind of life. Hope that helps!
Ahh, okay! If you should have spare time at some point to skip through again with similar choices, we made a new build that may or may not fix it. If you get stuck again, please let us know.
