Andy's experience was so strange he never really expected to ever meet someone who had been through it too so when he saw Sarah's post he had to read it three time to make sure it even said what he thought it said. For a moment he wasn't sure she wasn't a female version of him from another dimension. He told Charlie where he was going and headed out to get some food. He didn't know what she liked so he got pizza (because he'd never met anyone who didn't like pizza) and hoped she wasn't a vegetarian.
He walked fast because he wanted it to still be warm when it got to her. He didn't like the idea of her waiting because he knew how rough it was to arrive in the place with no freaking clue how that had happened. Close your eyes one place, open them in another on top of what she had just lost and just had to do. Losing time and space. He had some pretty bad and freaky news for her too. At least he had pizza and, just maybe, a little more understanding than most. It didn't seem enough.
He found her door easily and knocked firmly. "Hi, Sarah? It's Andy from the network thingy. I have food." He waited patiently for her, listening for signs of movement, that she was in there and okay. As okay as anyone could be who'd just had to blow someone away.
