While reading all 4 chapters you've updated, I have finally made a profile for Micah
This chapter really gave a deeper look into why Micah feels responsible for Joel so much. We can infer that Joel stopped talking when Micah told him to shut up, leaving him to feel guilty for both his mutism and (somehow) his mother's death. Feeling responsible for all the bad he feels he caused, he makes up for it by trying to replace his mother in a way (making Joel lunch in the morning, doing his laundry, and taking him to doctor's appointments; all things a mother should be doing). I also think Micah feels responsible to take over the role of his parents because his father blames him somehow as well. It seems strange that only Micah and not Joel was the one physically and verbally abused. It seems as if Joel was never the brunt of his father's anger.
That being said, I literally cannot wait to read the father/son confrontation !!!
Thanks for another great chapter!
