When Henry discovers the hidden floor compartment full of cash, as he is removing the floorboard, his hands are bare. A second later, as he removes the cash, he's now wearing disposable blue gloves.
Towards the end of the episode, it is revealed that Abe met Marco while standing in line to board a bus in 1965, with Henry and Abigail standing near them. But when Henry and Marco were talking in the prior scene, Marco doesn't notice that Henry still looks the same as he did 50 years earlier, even though he should have the appearance of someone well into his 80s.
