User blog:Kyrex18/Derek's Alpha status

a question i would like to know is that when Derek healed his younger sister Cora did the spark go onto her or did it just dissapear. now that he isn't and alpha now and Scott is does that mean Isaac and Derek belong to Scott's pack or are they both Omega's? because i noticed in the episode night school Peter was the one that bit Scott and made him transform, but in 3x14 Scott made Isaac's eyes glow.
