* AngstWhatAngst: In "Toy Surprise," we find that Mr. Parker never seemed perturbed by his wife's death. Sydney even recalled Mr. Parker told him "Life goes on" and resumed life as if nothing happened - immediately after the funeral, thus suggesting this trope. A DSA that Angelo had obtained even shows that exact conversation, but after Sydney leaves, we see Mr. Parker sit down and openly weep over Catherine.
* BetterOnDVD: Loose ends or not, the [=DVDs=] make it a lot easier to try to keep track of what's going on instead of getting one episode at a time.
* TheChrisCarterEffect: It became increasingly apparent that the writers had no real idea where any of the the ongoing mysteries of The Centre were actually going, nor any interest in resolving them.
* ItWasHisSled: Jarod having both a brother and sister.
* JerkassWoobie: Miss Parker.
* MoralEventHorizon: Mr. Lyle killing [[spoiler:Kyle]].
* SeasonalRot: Season 4. TheChrisCarterEffect was in full force, [[LukeIMightBeYourFather old]] [[LongLostSibling storylines]] were being recycled, and newer ones (like Mr. Parker on the run and the whole story behind [[spoiler:Thomas]]' murder) meandered. Those kind of complaints certainly cropped up in the first three seasons, but individual episode quality also began to suffer.
* {{Tearjerker}}: The end of "The Dragon House, Part 2." [[spoiler:Jarod's brother Kyle is presumed dead (though he is later shown to have survived), while he found his mother and sister - only to lose them again just as quickly.]]
** "Red Rock Jarod," where [[spoiler:Kyle dies for real in Jarod's arms]].
* TheyWastedAPerfectlyGoodCharacter: Mr. White, the enigmatic albino played by [[{{Saw}} Tobin Bell]]. Among other things, White acts as The Centre's "finder" for families that could be used as leverage. He plays a notable role in the Season 4 premiere, has been searching for Jarod's family and even tells him he'll [[WeWillMeetAgain "see [him] on down the road,"]] but he never returns.
* TheyWastedAPerfectlyGoodPlot: The first half of Season 4 sees Mr. Parker on the run from the Triumvirate. Not once does he ever cross paths with Jarod during this time.
* ToyShip: Young Jarod and Miss Parker.
-->'''Jarod''': I still remember the little girl who gave me my first kiss.
%% While this seems like in-world, the trope is pure audience reaction.
* TheWoobie: Jarod.
