* SugarWiki/HeartwarmingMoments:
** The ending of ''Solitary Vigil'', when [[spoiler: Bubbles manages to save Blossom's life and avert the events of ''Syndrome'' and ''Relapse'' by taking the blade, and manages to warn the Professor to never bring any of them back before passing away]]. Doubles as a {{Tearjerker}}.
** Another moment in ''Solitary Vigil'': Bubbles discovers that Bulba, the lone flower to survive the shockwave from the Doomsday Device activation back in ''Relapse'', was one of Blossom's components. In a way, Blossom was still with Bubbles through her ordeals.
* NightmareFuel:
** The various deaths, particularly [[spoiler: Blossom's first and final]] in ''Immortality Syndrome''.
** ''Relapse'' provides even more, including a [[NauseaFuel sickening moment]] which reveals what happens when someone attempts to resurrect another without all the pieces...
* TheWoobie: Bubbles, especially in ''Solitary Vigil''.
