The initial excitement over Donald and Douglas's bionic upgrade wanes when they discover that it can't apply to Bree, Chase or Adam (as their bionics stem from earlier technology). Only Adam can face their projected obsolescence with ease. Meanwhile, following a run-in with the law, Daniel joins the academy as its newest student, with Leo as his appointed mentor. While training, several students notably vanish. Soon all the former ex-soldiers (plus Daniel) are gone. An emergency message soon solves the mystery: Giselle has returned to destroy them all.
Did You Know?
The only season finale of the series to air as a 1-hour event. After the original airing, this extended episode (as other extended episodes before it) was divided into two episodes, parts one and two. See more
Daniel vanishes along with the ex-soldier students because Leo gave him the recent bionics upgrade. The recent upgrade only affected the bionic ex-soldier students because they were newer models developed under Victor Krane. Daniel was not one of them. The upgrade shouldn't have worked on Daniel, and he should not have vanished with the others.
^^^ Daniel is a lot younger than the others so he's considered a newer model. It shows much newer he is because his powers were barely activated. See more
