In fact he almost attempts to, taking a step forward and holding out his good hand--but Gary remembers that first meeting with Nill quite vividly, as much as he would like to forget how awkward it was, and he's long since made the connection that holding her is what made her so distressed.

It's weird, like...he gets in your head, and he's not really there but he's there. You know?" Yes, crystal clear description, good job Gary. "Shit, I can't wait to see the look on his face when I tell him about this!"
