WMG / Lab Rats

Eddy is evil/has been hacked.

The evil part is WMG?

• Actually evil, as in working for Douglas not as in being a jerk

Leo will get bionics

After the events of Parallel Universe, Leo may be in line to receive bionics of his own in his own universe. This is because the episode showed that there is a duplicate to everything in Leo's home universe, therefore, the 'geo-leaping' and 'lightning fingers' he possessed in that universe may be actual powers that either one of the other Lab Rats may develop... or Donald, realizing that Leo's not so useless, may have created a way to give him powers for an extreme emergency.

• Confirmed in You Posted What?! Part 2.

Chase really did join Douglas

This will be revealed in the season finale where Douglas returns. The plan has been in the making since Avalanche and it will have far reaching consequences. It will also end the season on a cliffhanger with the lab rats except Chase in mortal danger, controlled or exposed to the world.

• Jossed.

Adam is the only Lab Rat with a biological mother

When Douglas began making bioengineered humans, he could not make them perfect with just his own DNA. He found a suitable 'donor' and used that woman's DNA with his own to make Adam. When he made Bree, he had made significant leaps in the field of bioengineering, but found it near impossible to make a male (like he wanted) with only his DNA. However, he found a female to be more stable due to the double X chromosome as opposed to XY and settled for a girl. On his third attempt, he was finally able to perfect the process and make a male using only his DNA.

Chase's intelligence bionic only affects his literal intellect, but not his wisdom

This implies that Chase's so-called superhuman intelligence only allows him to perform feats such as processing calculations hundreds of times faster than a normal human and storing a ton of academic information in his memory, but this does not affect his ability to rationally reason or judge situations properly, as seen with the countless number of times he's made a simple blunder, or acted immature or selfishly to the point of driving an episode's entire plot.

Parallel Universe Lab Rats

In the alternate universe, the Lab Rats live with Douglas, who is a doctor in that universe. Their last name is from their father taking his wife's last name to distance himself from his family. That is why they and Donald don't know each other.

The person in the white mask is Marcus.

His body is covered because his exterior skin was damaged.

• Jossed. It was Douglas' new partner, Victor Crane.
  • A case of They Wasted a Perfectly Good Plot as Marcus' return would have been rather interesting.
    • Though, he did return in the season 4 finale.

Spike is not a glitch of Chase.

When Chase was originally designed he was to have a different personality and Spike is what's left of the dummied out program.

Douglas will be redeemed by the series end.

• Victor is going to take over as the Big Bad and try to destroy the Lab Rats. This will push Douglas to protect them from him. At first just because he wants his weapons back, but it will evolve to show he really does love them. This will eventually redeem him.
  • Confirmed from You Posted What??? on.

Adam will join Douglas of his own free will

Through out season 3 Adam has made cracks about how Davenport's not their real dad and that Douglas is Evil but Fun and probably has a minifridge in his evil lab. This could be evidence for Adam to go rouge.

Lab Rats will have a Boys vs Girls episode

Chase starts a war about which gender's better by saying that it's not their fault boys can do things better than girls can. Bree will retaliate. Then the bionic academy will be split up into teams: Boys and Girls. In the end, one gender will win.

Bree will turn into a bad girl in one episode

Sebastian returns and convinces Bree to rebel against Mr. Davenport and her brothers and friends. She almost nearly kills them.

One character will get to say "Shut up" instead of "Shut it"

Bree will unlock a new ability later on

Besides invisibility, Bree will recieve something like Ice Breath

Douglas is gay and likes Krane

Just listen to him talk about the guy.

Adam was originally supposed to be Killed Off for Real at the end of Bionic Island.

The scene in "Space Colony" in which Adam volunteers to destroy Dr. Gao's doomsday rocket and flatlines while doing so wasn't supposed to be a Bait-and-Switch, but the real deal: he was supposed to either burn up completely and be reduced to ash in his attempt to stop the rocket, or, most likely, succeed in destroying it but perish alongside it, with him consequently being mourned as a hero and Too Good for This Sinful Earth. Disney presumably vetoed it for being too dark and depressing, even for a show that's supposed to be Darker and Edgier than their usual fare, so the scene in question, and everything that happened afterwards, was rewritten so Adam just blacked out and survived the final two episodes.

This could be also why they had Adam opt to stay behind in the academy rather than join Bree and Chase in the Elite Force. Presumably, it had already been decided that Kelli and William would return for the Elite Force spin-off, while Spencer was free to leave the show and pursue other projects, with Adam's death scene being his big send-off moment. When Disney vetoed this and Adam's ending was rewritten, they had to resort to having him and Leo being put on the same bus.
