Ace was actually surprised by the suddenness of Senna's entrance. His pale cheeks burned bright red with embarrassment as he spun away from the two newcomers. "F*ck you, Senna!" He snapped which prompted Z to snicker. The grey-eyed woman looked towards Tim and Senna, waving and saying 'hi' despite no sound coming from her. Ace suddenly spun around in his chair, once his blush simmered down, to glare at his friend. "Did you really have to break down my door?" He questioned in an annoyed tone. Z had her hand on Ace's shoulder as she smiled down at him while he snapped at the two whom she did not know.
