Bridge's full name is Bridget and Jack's is JonathanThey're the only SPDs without a nickname. All their teammates have nicknames, and all their counterparts have nicknames. They can't be the only ones in SPD without a nickname.
The SPD become the Time ForceIn Power Rangers Time Force, Bio Labs is shown to be reverse engineering Time Force technology, including the Quantum Morpher. Wes still has his morpher at the end of the series as well. It's likely that Bio Labs managed to reverse engineer a good amount of the equipment and help form the Earth-bound chapter of [=SPD=}, which also explains why Sky's father is wearing a Time Force uniform despite not being Wes: after the equipment was reverse engineed for function THEN' the gear had its appearance changed to incorporate a new design. By the year 3000, we will have discovered the other ether technology.
Boom will become SPD Blue after the seriesYes, he washed out of the Academy, but he was able to put up a pretty good fight during the Grand Finale, and even in the pilot he was tossing around the three best students in the Academy. Odds are he was made a Ranger to replace the spot left by the retirement/promotions in the final episode.
The time traval turning people into a ball of light was total BS
Other squad members got promoted.After Jack's departure at the end of SPD, and Sky and Bridge's promotions, referenced in Once A Ranger, that leaves the core B Squad team with only three members (Bridge as Red, Z as Yellow, and Syd as Pink). Considering that their Mega Zords are designed with a team of five (or more) in mind, this would cause problems if they ever actually needed to take up their powers again. They found SOPHIE again and she became B Squad's Green. When Sky and Bridge were promoted a second time, SOPHIE wasn't and they picked a cadet from C Squad to become the new Blue Ranger.
Nova is Z's daughter.
