Commander Susan Ivanova

[Ivanova is trying to remove her collar. The video has several minutes of her fussing and tugging on it, and finally trying to pry it open when the bar slips and slices open her hand.

Hissing, he holds the injury with her other hand. Although in a few minutes she's more shocked by the fact that she has formed red lion's claws on the injured hand out of her blood. The surprisecauses the sin to fail and turn back to blood which then spatters on the floor.]
