[Freedom is a strange thing: the lack of ties, but also sometimes the lack of roots or anchor; the inability to turn back. Lenka's found his anchor again in his Unit, and even here they keep him grounded and able to find his way, or at least the road signs. In some ways, it's about what's right and necessary; at the heart of it, he just wants to see them again.

So even if they don't have the same home, exactly, he can still pass a little of the warmth and strength of those connections to Julius with the handshake, and the small smile he gives him.]

There's a lot of worlds out here. [in a way, it's a reiteration of the hope he clumsily expressed when they met, and it won't be the last time; and if Julius is ready to go, he can also help pull him to his feet] Thanks.
