It’s that time of year again!
Re: wolf eye color- the first time I watched TW was before 3A aired in a pop-up video style marathon on mtv. One of the "facts" they showed during a season 1 episode was that the eye color was related to born wolves vs. bitten. So yeah, I'm pretty sure that blue eyes = "killed an innocent" thing is just some BS they pulled out of their asses after Colton left. And while Jack wasn't //exactly// a born wolf, if he had wolf blood it makes enough sense for him to have had blue wolf eyes.
