Reader deep thought: Tuor and Túrin. Two peas in a pod when they started. But their life stories could not be more different. What would have happened if Tuor had spoken to that tall, dark stranger he encountered at Irvin? Probably something bad (even were it no fault of the stranger), and somebody would behave badly. Whatever might have transpired, chances were it would have driven a trident in Ulmo’s plans and given him a litter of shark pups. So sometimes it does pay to heed the elders: Don’t speak to strangers!
Reader deep thought: So the only Calaquendi who saw the Two Trees but never lived in Valinor, ruled over his people, the Sindar (essentially the high-born of the Moriquendi), who also did not cross to the West. The intriguing question remains: was it really happenstance that kept Thingol in Middle-earth? With all that happened further down the road, and the connections that tie back ultimately to the Sindar or even Thingol himself, perhaps the Highest Power of them all agreed more strongly with Ulmo’s opinion than anyone realised, and had a plan that CANNOT.BE.DENIED, regardless of the Valar’s suppositions.
