He’d be ecstatic!
His hacking skills, unlike in the space war, would be properly recognized by you, so he’d be able to implant many enhancements to your ship without being outed to the Alternian government. He’d build many proper seats for chilling (like in his hive, just without the faux horns) and if possible, be able to dismantle drones to use their parts as engine pieces. In the big day, he’d help stock up plenty of food for everyone to be full and happy during the trip. He is initially surprised by the humongous number of passengers, but is happy since he knows that it will make YOU happy. He acts as a co-pilot in the travel, and you couldn’t be happier knowing that all of your friends and quadrant mates will be in a better place soon.
