That scene with Arnold visiting his wife?
Not to sound too dramatic here or anything, but I had to stop watching just to absorb that for a moment, when she was talking about their son? That she's wanted to keep living, to hold onto life for as long as she could...so that the memory of her dead son wouldn't die with her?
Jesus H Christ, that just hit me right in the feels. Not for any experience of my own, but just how poignant that was, how well that communicated her loss, her love...to keep his memory alive for as long as she was able...frigging brutal!
