I haven't read through the thread much lately, so sorry if this was talked about.

Regarding Trubel being Nick's sister: If Kelly is the mom Nick would have known about Trubel since she was born in 1993 and Nick was with his parents until 1994. I guess it's possible that Nick's dad had an affair or something, but I'm pretty sure you have to have Grimm ancestors/relatives to have a chance to be a Grimm and Nick's dad wasn't a Grimm, so what are the odds of him having an affair with another Grimm or someone with Grimm relatives?
