After finally
meeting and talking with Dark Blues, Chaud had gained the courage to talk to Proto. Which was something he should've done a long time ago.
He wanted to make sure that no one else was around though, so he waited until Enzan and Blues left for the Nexus and he was sure Netto and Rock weren't coming back. Then he took the PET out of the recharger, hesitated, and pulled the chip Proto had used to transfer beforehand out. He made a mental note to give that back to the younger Enzan next time they met, and slipped in the upload chip Netto had left on the table. It was marked 'RT Program', so he assumed it installed the program that let Navis transfer between worlds. He hit the power button and let Proto fully materialize and wake, but activated the upload before he had a chance to say anything.
