in the Pilot when Adalind woges was it involuntary, was it ADalind confirming Nick was a Grimm, or had Sean already made Nick a target and it was Adalind way of saying I am coming for you. The involuntary would be strange because Adalind does not woge any other time in Nick presence involuntarily. To prove Nick is a Grimm why if Sean said he was a Grimm she has never checked on her own since. As a show of attitude. That is something Adalind has done several times, woge to show how tough she is. AS a show of attitude would mean Sean had already told Adalind who Nick was. Amazing Hank did recognize her when the meet as the women NIck was eyeing on the street.
