Waukeen naturally didn't believe that line of reasoning.
She might seem a little naive in some respects, but she wasn't stupid.
This Silver Dragon had managed to successfully outmaneuver Tiamat even when facing an absolute disadvantage, forcing her failed descent upon the Prime Material Plane. That alone showed this fellow was no "good thing."
Would such a "scheming" dragon really possess thoughts so kind and noble?
At least shift your alignment to lawful good first before saying that!
Compared to that, she would rather believe her initial conspiracy theory: this fellow wanted to ascend to godhood himself!
And once someone believed in another deity, unless that deity generously granted them the position of a subordinate god, it would basically be very difficult for them to rise on their own.
Still, Waukeen considered herself not the sort of goddess who liked to twist others' wills out of thin air. If he didn't want to, then he didn't want to. In any case, the things he was doing now were greatly beneficial to expanding her divine portfolio.
Originally, she had only wanted him to believe in her so they could cooperate more conveniently. Given the strength and potential he had displayed, so long as he didn't die young beneath Tiamat's coming retaliation, he might truly have a chance of rising.
