Could have been the end of Zoe's promising modelling career had she been badly beaten with that crowbar. Fortunately, the assailant only hit her hard enough to make her unconscious while ensuring that her features remained unblemished. Not even a hair on her head was put out of place by the impact.
The assailant showed admirable restraint in the way she wielded the crowbar and is therefor, worthy of praise. It's better to try and avoid gratuitous violence where possible. I also applaud the fact that she had the courage to show her face although Annabelle did offer to lend her the balaclava.
