With Clank having taken his role, he realized that he could not leave Ratchet behind. When Alister Azimuth attempted to access the Orvus Chamber, Sigmund tried to stop him, successfully landing a few hits on the General before being thrown back. Later, Sigmund helped Ratchet and Clank escape planet Morklon by creating a Time Portal for them, as Sigmund had the Breegus Almanac installed allowing him to access past events in the Breegus System.

Sigmund was left in the Clock while Clank was taken to Vapedia. Sigmund eventually accompanied Clank into the Orvus Chamber, but him and Clank were both immobilized by Lawrence who had followed them inside. Sigmund then proceeded to show Clank around the Great Clock and explain its functions and abilities to Clank, though a lot of the time he either played a tutorial video for Clank or directed him to a Mnemonic Chamber where Orvus trained Clank in Clank's subconscious. When Clank awoke, Sigmund repaired him and introduced himself. Sigmund helped guide Clank to safety, before Clank hit a dead-end and Lawrence immobilized him. Nefarious damaged the Clock using the Hypersonic Brainwave Scrambler. When the Zoni took Clank to the Great Clock, Clank was awakened after Dr.

Sigmund had a lot of respect for Orvus, and alongside Orvus, helped prepare tutorial videos for Clank when Clank would eventually become Senior Caretaker. Sigmund was originally a cleaner bot on Viceron, the planet on which Zordoom Prison is located, and was selected by Orvus to become Junior Caretaker of the Great Clock.
