Follow that Finnwinch Detentionaire : Season 4 Episode 1

The episode picks up where the previous left off, the pyramid opens revealing symbols. With a device composed of eye-pieces by Earl Nigma, Finnwich is able to see the invisible projections on the symbols, seeing "where it all began". When Lee escapes after being attacked by Hazmats, the Pyramid once again triggering his martial prowess as his tattoo glows, the Council arrives to take Finnwich after he blows up the pyramid, so they can never know its secrets, killing Cassandra's brother, who refused to run, in the process and hides his book and device for Lee to retrieve. Meanwhile, Biffy escapes the falling aircraft, Holger believes he has superpowers (in this case, enhanced stealth abilities and X-ray vision) after waking up from unconsciousness in the detention room with Jenny, Cam and his group attempt to find out whose fingerprint was on the letter and later Tina is freed by Lee. After they all meet up, Tina and Jenny study the book with the device, and Lee, Biffy and Holger proceed to find Finnwich. The boys find a hideout where they see Finnwich, Lynch and the female council member are carried to a submarine to be taken to Coral Grove, where the Council sends people who "know too much". Elsewhere, when the book mentions Coral Grove, Tina proceeds to tell Jenny everything she knows about it (information she gathered during the short webisodes). Grayson tells Cam he cannot find a fingerprint match and all but Cam and Cyrus had quit what they love.
