Walter scribbles notes on his desk at the end of his bed (which is, you'll remember, in the living room of the Bishop house) as Peter walks in (the thunder and Peter's soaking hair and shirt letting us know that it's raining outside) with a box of stuff that he dumps in front of his dad. "What's this?" asks Walter. "It's a present. Your father's work. I had Franko give me everything that wasn't totally destroyed." Walter goes from grumpy to giddy as he goes through the box's contents. He comes across an old photo of his father that he shows Peter. It's a yellowed photograph of a bunch of men in tuxedos, with some sort of Nazi decoration behind them. "Robert Bischoff," reads Peter, confused, and Walter explains that Peter's grandfather changed his name when he came to the States. "Your mother always said that you shared his 'noble brow.' It's a pity you never got to know him. You two would have gotten along very well, I think."

Peter smiles at his dad and stands up, and then says, like Columbo, that there's just one more thing that doesn't make sense: "If the formula for the toxin didn't come from your father's notes, how did this guy get it?" Walter figures there are some mysteries that are destined to remain unsolved. He thanks Peter for bringing them back and continues looking through them, as the camera zooms in on a sepia-toned photograph that could very well be a young John Noble as scientist Robert Bischoff. In the background is Hoffman, looking pretty much exactly the same as he does today (well, yesterday, anyway. Before he died).
