Trubel turning up at Marie's would have proven Kelly survived the crash. Yes, exactly. Aunt Marie told Nick that he was "one of the last Grimms"...and they do appear to be very rare. So, this Grimm bloodline that Nick is from, may be one of the last ones on earth. They didn't give us enough of Trubel's back-story to exclude the possibility that Trubel and Nick are related in some way. In fact, they left it wide open.
