"Heart of Glass" was a captivating episode.The episode was better than I expected. The A case involving the dead woman in the rose petal filled was the most interesting case. The case was perplexing at first with the confusion of how the woman died. But what was most interesting was that she was not the primary target. She was shocked to death but it was because of a bullet that was fired to kill Mrs. Ballard, in the apartment above the woman in the bathtub. Mrs. Ballard's husband tried to kill her but missed and the bullet got lodged in the brain of Mrs. Ballard. Interesting Plot. The most amusing part of the case: Danny finding out that Mac and Peyton were dating. The B case was to me, interesting. Stella's troubles continue as she was cut on the glass that was at the crime scene. The glass contained the blood of the victim, who was HIV positive. All throughout the episode , Stella hid her accident from Mac and her colleagues. This will be interestin as she has to wait for 3 months for the results of the blood test. Over all, great episode!
