This will likely be my final post in this thread. I'll begin a new one to provide further updates.
He is continuing to stabilize, and he's starting to wake up. He is coughing, producing tears, and grasping our hands. The doctors say these are not necessarily what are called "purposeful" movements yet, and that is what we need to see in order to be encouraged neurologically.
Once he is stable enough he will be taken for an MRI of his brain.
He will survive, but in what capacity is still unknown.
Thank you everyone, I cannot thank you enough for helping see me through this awful time.
