Recap: Transformers Prime S 2 E 17 Out Of The Past
The episodes begins In Medias Res
(of a sort) as a captive Arcee is dragged by a pair of Vehicons before Starscream. Starscream has intercepted an encrypted transmission and wants Arcee's access codes to decrypt it. When Arcee refuses, he tries to force her to comply by threatening another Autobot he has captured... Cliffjumper.
Arcee has been having a flashback to an incident on Cybertron as Miko and Ratchet try to help a recovering Bulkhead regain full use of his legs. Though concerned for her friend, Miko is pushing Bulkhead hard to recover, enough to make Ratchet protest. In frustration, Miko stalks off to the top of the mesa to brood.
Arcee decides to come up after her. She tries to tell Miko not to be too hard on herself or her friends because of their situation, something she knows all about after what happened to bot Tailgate and Cliffjumper. Arcee tells Miko about what happened shortly after losing Tailgate.
The previous flashback continues as Cliffjumper is thrown into a cell with Arcee. She is put off by his talkativeness as he searches for a way out. Meanwhile, Starscream and Soundwave discuss their failure to extract the information. Soundwave suggests that they take them to Kaon and get assistance, but Starscream is reluctant to share his glory. Soundwave throws back a recording of his own words saying how important the information is, and Starscream relents. The two are brought to Kaon and introduced to their new interrogator: Shockwave.
Using a cortical psychic patch, Shockwave extracts the codes from Arcee's mind, seemingly taking her offline. The encrypted message is from Optimus Prime, giving his location on Earth and calling for other Autobots to join him. Shockwave has been working on rebuilding a Space Bridge, and Starscream plans to drop his forces right on top of Prime. Arcee, who was faking being offlined, frees herself and manages to rescue Cliffjumper (using his big mouth as a distraction), and find out the location of Shockwave's Space Bridge. Cliffjumper and Arcee manage to get to the bridge and sabotage it, using it to jump to Earth. Shockwave tries to stop them in the middle of the Space Bridge, but Arcee defeats him and they make it to Earth just as the Space Bridge collapses, seemingly leaving Shockwave mid-transit.
On Earth, Arcee finally comes to accept Cliffjumper's friendship and officially makes him her partner as they set off to find Optimus Prime.
