Oh. There's this look of realization on Tommy's face when she gives Billy's full name. Because he's heard her name before, a few times, and he's put it together at last. The 'little red-haired shit' that likes to skateboard and listen to the Walkman that Tommy had been so careful in repairing.

"You're her. The one who had the Walkman that I fixed, and the tape he protects."

Billy treasures that Kate Bush loop like it's something sacred, and man, Tommy doesn't know all of why, but he's heard enough. That Billy did his best to keep his father's attention off of. The one that had been a source of conflict for Steve and Billy not long after Billy got here. Which of course Billy wouldn't want Tommy saying.

"Yeah, I'm talking about Billy Hargrove. And I can't really say more about him than that, because, I mean, you know him. He's a private guy. He'd hate if I gave you more than he wanted to tell you himself. But I don't doubt he'll want to see you."

Damn. He can't linger here. The question is does he risk the storm to start them walking back toward town? He feels like he should.

"Flash? That's a horrible name for a superhero. No. I'm fast like Quicksilver, or Northstar. Though Northstar cheats because he flies. That's just evading all the difficulty. And I think the city's that way. We should get moving. They're going to want to see you. All of them probably. I'd be an asshole if I didn't get you back to where they could see you."

Because while it will upset some Hawkins people that she's here, they probably really care about her, just like Billy does.
