* Josie and her mother's relationship in the episode "Culture".
* The scene at the end of "Hologram" when Vaughn finally [[spoiler: see's the Holographic message his mother has sent to him from the future]]. It also doubles as major [[CharacterDevelopment character development]].
* Josie and Professor Z's discussion about their parents in [[TheMovie The Movie]]. It's one of the few times in the series where this type of conversation doesn't come off as a [[ChekhovsGun Chekhov's Lecture]] and/or have any sugar-coating; not only are Z's words profound and eloquent, but the acting is quite good here and really helps make the scene resonate.
