If it were to be OK for him to regain it, I was either planning on utilizing a options happen here, which would be either to regain the technology that would allow it to work at a later date or possibly ask if someone arrived with the technology. The other option was to have Hinata possibly start working on building up to that tech with all of the talents that he has at his disposal and utilizing the things he's seen with the teleporters / nanobots + Dunamis to come up with an alternative way to utilize it; of course, I'd make sure that he wouldn't be able to reach that point immediately / it would take him a few months to pull off and I'm cool if that's not possible, either!

I'm completely fine with him just regaining it as a flash drive and him not having the ability to access it overall and to just... have it as a trinket, too, as another alternative. He'd just be happy to have it with him since he's sentimental.
