Yes, I had a tear in my eye too, even though Harold is not even one of my favourite characters! I guessed that Lou would be hidden in the mobile home.
I'm already sick of Zeke being a sullen little brat. I know he's been through a lot, so I should be more understanding, but does that kid ever smile? That storyline seems kind of weird - as far as I can tell, he hasn't been told that Susan and Karl aren't his real parents, that his real parents are dead, or that he has a sister called Katya. And you can guarantee that his first memory will be the time Karl chose to go to Libby instead of him in the collapsing warehouse!
And don't get me started (again) on Bridget.
