The mention of the loss of their ship triggered a flashback in Ratchet. Bumblebee chided that if they still had a ship, communications wouldn't be a problem. Once there, the Autobots attempted to build a communicator, to warn the Elite guard that Longarm is really a Decepticon spy. Sari epressed her anger at Sumdac's secrecy, and chose to return with Optimus, to the Autobot's Manufacturing Plant base. When they refused to leave Sari manifested energy blasters from her hands and blasted them into the elevator. Sumdac ordered them off the property, after Masterson threatened them about the loss of his Headmaster unit. They arrived back to Sumdac tower to find Isaac's lab trashed and inhabited by Porter C.
He told her that he found a small liquid metal form, and that Sari appeared after he touched it. Sumdac apologized for not telling her, but he wasn't sure where she came from. Sari derided Sumdac for not telling her about her robotic origins. Meanwhile, on Earth, Sari and Isaac Sumdac rode back home inside of Optimus Prime. Starscream panicked, but Megatron calmed him by noting that the gigantic Autobot was offline. Before they could celebrate, Omega Supreme warped in behind him. It didn't seem to go well for them, until Starscream became angry, transmuting a gun from his mouth and blasted the stasis cuffs off of Megatron.
Elsewhere, in the depths of space, Starscream (merely a head) and Megatron bickered, while Starscream tried to free Megatron from his stasis cuffs. The Decepticon infiltrator informed her that her group, "Team Chaar", would have to wait for Megatron to Transwarp to Cybertron before the could invade. Rodimus challeged the Decepticons, but Oil Slick mocked him and threw a vial of green liquid at Rodimus, causing him to collapse and he screamed "Cosmic Rust!" Strika then reported their success to Shockwave.
Strika ordered Cyclonus and Oil Slick to free Spittor and secure the perimeter, but the were interrupted by Rodimus. Strika scolded Blackout for taking the Space Bridge offline, but Blackout simply apologized and reactivated it with a stomp. The battle seemed to be turning around, until Blackout arrived and blasted the whole planetoid with his EMP. Rodimus left Spittor pinned to the ground by his tongues. Oil Slick and Cyclonus took Ironhide and Brawn out, while Rodimus repelled Strika and Spittor. Back on the Space Bridge planetoid, Rodimus rallied Brawn and Ironhide against Strika and her crew. After Ultra Magnus signed off, Longarm transformed into his true form: the Decepticon Shockwave. From Cybertron, Longarm Prime reported that the Space Bridge Nexus was fully guarded. Ultra Magnus hoped to keep the Decepticons from transwarping an invasion force onto Cybertron. On the Autobot Flagship, Jazz received Rodimus' distress call, but the Elite Guard didn't have the resources to spare, as Decepticon attacks at all outer Space Bridge outposts had them tied up. Rodimus appeared, and contacted Elite Guard command, asking for assistance. She became a living bomb, aimed right at Brawn and Ironhide. The Decepticon then spat her back out, covered in explosive orange goo. Red Alert provided medical assistance to HotShot, but Spittor grabbed her with his tongue tendrils and swallowed her. Hotshot tried to repel Strika's missile attack, but received damage to his leg. Ironhide, Hotshot & Brawn were under assault by Cyclonus, Strika & Oil Slick.
The Space Bridge is on one end, an Autobot base is on the other.
