Haha, the Rakata are REALLY unbalanced, which is fun xD

 I think what you proposed would work out well. Being vulnerable isn't exactly something either one of them would be comfortable with(obviously Yerbol is more comfortable, but no one LIKES being vulnerable). Sharing insecurities, fears, hopes and all that through breaks in action should help. I'll also assume that training together and helping each other through the breakdown of known civilization will help bind them together. We can plan certain sequences or moments to help push the relationship along...kinda like we've been doing and what we just did with the argument.
