Khal pondered for several minutes in one place as he tried to calculate the pros, cons, and every possible outcome of this 'gamble', but no matter how long he mulled over the things over and over again, he found out that there were more cons than pros and it didn't worth the risk.
However, because of the gains he could mayhap obtain if he decides to help Nova, he didn't immediately throw the idea of helping away, but instead chose to ask, 'And how can I be so sure you don't lie to me? Or what good do I have from helping you except for remaining in your debt forever? I hope you know I am not a Celestial Being, thus for me reaching the Sixth Realm is quite unlikely. Or at least currently that is for me.'
[You indeed have a point.]
Nova remained silent for minutes before suddenly she sighed and started to talk.
[Then how about this. We will make an Eternal Oath and you will have no reason to fear me nor feel wary when I try to help you.]
