I know Scott is a true Alpha and on various occasions his eyes turn red like trying to get to his boss etc. But I have watched this series over 10 times and I just noticed something this time that I have not been able to find any answer for.

In season 1, when the alpha has the group stuck in the school and Scott is in the gym trying to get the janitor's keys, after Scott throws the molotov cocktail and it doesn't explode the alpha slides Scott across the floor and lets out the fierce howl which triggers Scott's transformation. Now briefly in his transformation for literally about a second his eyes go from red to yellow. Why would they have done that?

Also in the same episode, just curious why his houl triggered something with Jackson's claw marks on his neck?
