Sabrina took a swim for a few minutes, rinsed, then dried herself. Ivanka ambushed her when she entered their house, stabbing her 16 times in the navel while she begged her to stop, staining her pants and floor with lots of blood. After Ivanka stopped stabbing her, Sabrina fell with the knife stuck in her navel. She vomited blood and convulsed before she pretended to die. After Ivanka left her alone, Sabrina took a knife from the kitchen and went upstairs to look for Ivanka, who was chilling in bed. Sabrina rushed her roommate and stabbed her in the navel. Sabrina twirled the knife until Ivanka vomited blood and died.
In the end, both psycho roommates died with a knife stuck in the navel.
