What would you fix in this scene?

Almost at the last part, i think i read that Zachary just walked towards Zoe, and just left... I wonder if Zachary is violent in a way, because he should have hurt her, and since he threw the bottle of wine, but if he isn't really, then he should have slapped her, then left, or at least showed a little bit of anger (or even more) on Zoe. maybe holding her arm, and shaking her wildly while shouting at her. Maybe even add somebody downstairs complaining, and went up, and saw Zachary hurting Zoe, and he/she helps her, and in the end Zachary leaves.
