tom, migg, Stevie real, gerri fictional
migg is real, he buys wine, he lives in tom's house are real, Gerri is fictional, tom got hit (there is also an element of worshipping CB who wants to imitate him), and subconsciously understands that migg is just using him but doesn't want to face it, so "gerri" helps him "get rid of poverty" and "refresh". That being the case, stevie is also real. Finally, seeing Migg soaking in the bathtub is also a real reflection.
With that said, "gerri" came to "salvation" tom and said: you are not CB, you can't go on like this, everything is fake, migg heard tom talking to himself in the bathroom (tom thought he was talking to gerri) , so scared that he quickly hid behind the door, Tom couldn't see him, so Tom even more suspected that Migg didn't exist (but he believed that gerri did). Then I understand that migg trembled and said to tom: everything's alright, tom? (It seems that the original words are this). Tom lost his mind, believed gerri, drowned Migg, and stevie found the body.
