Some fans argue that the events of this special are incompatible with the Dino Rangers' later unfamiliarity with the SPD Rangers in "History." Note the following:
In this special, Kira saw the following visions (voices not matching later SPD characters):
- five morphed SPD Rangers confronting an Orangehead
- R.I.C. (Delta Base in background), SPD Rangers using Canine Cannon (called "Mega Cannon")
Ethan then saw the following visions (voices not matching later SPD characters):
- five morphed SPD Rangers calling for Zords (Delta Base seen)
- Delta Squad Megazord forming, fighting Giganis (dialog doesn't match "Idol")
A voice then told both teens the following:
- "The future of our planet are the Power Rangers Space Patrol Delta."
- "Earth has allowed alien beings from distant planets to co-inhabit the Earth."
- "The Troobians have now set out to take over the planet."
Both then saw additional visions:
- five morphed SPD Rangers using jump tubes and deploying their Zords
- Delta Squad Megazord fighting a drill robot (see "Shadow, part 2")
Finally, the voice noted, "These are images of the near future — your future." The rock then ran out of power, leaving Ethan and Kira craving more knowledge as the special ended.
(For what it's worth, note that none of the voice-overs for SPD characters heard in these visions matched their eventual SPD counterparts.)
Then, in "History," the Dino teens experienced the following:
- The trio suddenly found themselves in an observatory, where Broodwing welcomed them to "the future" and intended for them to help him "destroy the planet," but they grabbed their nearby (depleted) Dino Gems and ran.
- In the city outside, the teens were attacked by Krybots; Broodwing explained their powers were "legendary throughout the galaxy," wanting them to fight alongside him.
- After unmorphed B-Squad had deterred the villains, Jack identified his team as "Power Rangers Space Patrol Delta"; at this, Kira objected, "you can't be the Power Rangers," because, as Conner explained with their gem-laden bracelets on display, "We are."
Later in "History," the teens restated off-camera exposition:
- Ethan (curiously): "Somehow we've been transported years into the future…?"
- Kira (confidently): "…and this is a state-of-the-art command center that trains elite fighters to become Power Rangers."
- Conner (perplexed): "…and Earth is under attack by an army of aliens and giant robots?"
The three teens were also startled by Doggie Cruger in the command center (Kira was confused by his canine appearance). When asked how they'd ended up in the future, Kira explained, "Well, things are a little fuzzy, but we were on our way to the reunion at Reefside High."
Whether this sequence of events suggests an incompatibility between SPD and the "Before It Began" special is up to you. Setting aside this compatibility question, no events from this special have been referenced in the actual series.
