The thing about Chuck I keep coming back to is that... this is a neurological condition causing his problems, and... it's not going to get better. At best, we could've maybe slowed or paused the progression for a while. But sooner or later (and it seems like it's "sooner") he would continue to get worse.
But I want to keep him in those happy, comfortable moments he has as long as I can... I just don't know how long they will last...
