Goris walked through the metallic corridor of The Mothership at a turtle's pace, he had nowhere to go he just liked to walk through this gigantic ship's Halls and he did this every-time he wasn't tagging along on missions. 

the metallic walls brought him comfort for they reminded him of Vault 13, of his home, so much so in fact that he would sometimes expect to see one of his many brothers to walk right past him. 

but of course they never did Goris let out a sad sigh at the thought of home, when he first arrived they tried to find his universe but the stepper box was broken beyond repair (as in it blew up) so it was impossible to trace the data back to his previous location. Not to say they didn't try but in the end it was futile and they eventually admitted defeat and informed Goris of their failure. Goris took it a lot better then anyone would have expected he accepted it and he sort of knew that wouldn't be able to him back. 

so when the news came he took them with dignity. 
Goris as thought about his past he noticed that Mizuki was heading towards the transporter hub "Hmm?" Goris's curiosity was peaked, he knew that she was supposed to be heading towards a meeting, so why was she heading towards the transporter hub? that what he intending on finding out so Goris proceeded to follow the sailor scout into the hub and he entered just as she teleported away, so he quickly shielded his eyes from the Flash. 

he let his arms drop when felt it was safe for him to open his eyes. 'Now where could she have gone of to?' Goris thought as he stepped onto the transporter pad, he began looking through the machines's stored archives of recent transports it didn't take him long finding Mizuki destination. 

"Hmm it seems she was following a distress beacon it would be for the best if followed" Goris quickly input Mizuki's location and activated the transporter then with a quick flash he was gone
