Zach was quite glad Theo hadn't just...disappeared off to fight whatever was going on with people. He had been quite nervous that Theo was going to go do that, or something. But they still hadn't seen as much of each other as Zach liked. It pleased him, through all this, that there were still a lot of amazing people in the world.
"Theo!" Zach greeted his best friend enthusiastically, "Come in, come in!" He didn't have anything on at the moment, but that was easily fixed. Slightly belatedly, Zach decided to give Theo a hug, and it was a large one.
