[@Akayaofthemoon] Looking back at it Spinel wouldn't have actually seen him put her in the bag, but she should have seen Reggie with Eve in a bag and Sodalite trying to grab her back from him.  Spinel knows that Sodalite is one of Evenkite's more well-liked members of the group and they don't really know Reggie.  She also knows that Evenkite isn't trusting of new people to begin with and probably wouldn't have willingly been brought on Bloodstone's ship.
