You forgot a key part of waht he might have said had they spurned him, "Oh and by the way, they have this guy who's supposedly head of the rangers and who apparantly grew up under Elrond's protection. He's claiming that he is the King and has plans of marching back here with his band to claim his throne, and it seems the elves and Stormcrow support him in this. In fact, this so called king actually has plans to MARRY an elf once he has conquered us. In other words, not only does Imadris not trust us or want to help us, they are actually plotting to replace us with thier own guy, who grew up with elves, is going to marry and elf and is probably more than half elf himself."
