So uh... Your father tried to make you come to the baby, so your parasite's babies could settle in the Matthew. Won't it activate the next time you hug your son? Or does it have to be a conscious choice?

And what about the headaches? The real father mentioned that "you're almost bursting" - won't that mean the eggs would burst out of your head eventually? How would you even go to the doctors for this? Would MRI show something? Did going out to the storm calmed your headache down, so you'd just need to take a shower whenever it comes, or did it kill all the eggs and that's why you could take a shower and not worry about the water?

At the end of the day - you're what separates boomer fathers from current ones. No emotional distance, no listening to the father just because you're his son. Good job. If you can survive this, you'll be a great dad.
