Keeping my studies up. I'm sure you haven't touched a book since you've been home.

[ All assumption and all fairly accurate on Gareki's part. If you could consider his tinkering being studies. However, what he isn't really saying is that he's also been working for cash. Working to keep himself and family above water, despite not seeing them. What's more, he had to find funds toward the device he was building. ]

[ Gareki turns to a machine set into a wall and starts pressing buttons. He orders two tickets, pays for them, and then hands one to Yogi. ]

Don't lose this.
