Pain Killer

one minor flaw that is a major issue for me when it comes to believing in the story hence being immersed. Identical twins are not exact replicas of each other. Once you've been with them enough, you will know who is who without asking their names. I know coz I have cousins who are identical twins. Either the writer plainly ignores this fact hoping his audience would too (or be none the wiser) or the writer(s) is/are completely ignorant about this fact.
