I almost forgot about this one. But then the creepiness of monnie44 's and brandywine421 's latests installments reminded me about my blood- and death -themed fic. Plus, after miss_begonia totally killed me with the final part of With or Without You, I needed some dead!Marissa but not dead!Ryan. This instalment is less creepy and more wierd, but I guess that is just my brain.
Part 5 of brandywine421 's birthday fic D is for Death / Chaos Theory
