WELCOME, SARA JOHNSON! (Sarah?)
In the diner, Sam and Maggie go through a weird conversation to remind us of who Mr. Wells is, while perhaps "demoting" him, making him seem less important, so that we won't notice or think it's strange when we don't see him much in the future. I'm reading all that into it of course, but it's more fun that way. Maggie mentions Mr. Wells, last referred to just as "Hotel Clerk" in the credits awhile ago, Sam feigns (?) ignorance, then I think Maggie makes fun of Sam for it, and mock-reminds him, knowing Sam could not possibly have forgotten someone they see every day... aka "that jerk in the hotel!" No longer her boss? Just a joke?
That paragraph above lasted much longer than the exchange itself.
And considering Sam's constant, barely-under-control, almost blind panic, it's to his credit that he stopped Maggie from perjuring herself. Compare and contrast... Roger just has or soon will gave an opportunity to make that choice, though not with a family member [spoiler](that he's aware of).[/spoiler] (I'm usually an ep or two ahead so I don't remember if it was this one.)
