I figure Cassian would follow Penny to the ends of the earth, so presumably he would go with them if they did something like that. And Jinx is even easier. They would just get to their destination and discover that she was hiding in their luggage. 😁
And I kind of half assumed there would be some sort of investigation of Pridwyn and Titania in 'Bliss', given that she's already suspicious.
Either way, can't wait to see where her story goes.
