Leia Artemis escaped off Fastoon during Tachyon's attack, but was separated from her husband and son. She soon had to make peace with the idea that she was the only Lombax left in the Polaris Galaxy. She had no idea about her son making his way to Solana. Twenty-two years later, Clank is missing, and Ratchet's life is about to change forever on Torren IV.

Ratchet never talks about the time Clank was missing, so when Clank accidentally finds a voice recorder full of Ratchet's notes and thoughts during the hunt he can't help but listen. He just didn't know he'd break his own heart in the process.
