Like Tim I reccomend rebuild on the second spoke(fatigue) failure. And that does not even apply to your situation, sounds like something must have struck the spoke just right, in the accident, to get a failure. One thing tho. Spoke failure anywhere except the threads or J-hook is pretty odd. I have seen a couple of wheels on newer bikes have failures similar to yours, where the spoke broke on its length. We would replace the broken one only to have another failure in a few days. Turns out there was a batch of bad stainless spokes that were flawed and would just,...break. So, stick a spoke in it and if you have a failure again, rebuild or replace the wheel. If it is a newer bike and you have another failure, take it back to the shop you got it from and have them check with the maker for reports of spontaenous failure.
