Chris is going to explode from horniness.

It's probably a good thing for both of them that Marlo doesn't know that. 

Chris is not going to be the person who stops cuddling Marlo.

Eventually Marlo says, "You should probably be heading back to Stark Tower soon." 

"Okay," Chris says in the tone that means "yes, sir."

"I'll come by. Good night." 

And Chris returns home and does not download Grindr and search for a tall blonde man built like a Greek god who has an interest in spanking and gentle domination.

Instead, he masturbates furiously.

And Marlo sleeps, and doesn't notice until he wakes up in the morning how protectively he's holding his pillow, and then starts doing entirely too much research on what college is like in the 21st century. 

In the middle of the afternoon someone knocks on Marlo's door.

He's sort of half-expecting it to be Chris again, when he answers. 

It is not in fact Chris. He has no idea who this person is. 

"Hello," he says. 

This person steps inside. He is more than six feet tall and his shoulders are almost as broad as Marlo's, and when he unfurls his wings they brush both sides of Marlo's quarters.

"I'm Chris's brother Ron."

Aha. 

"I'm Marlo. It's good to meet you, Ron." 

"I want you to know," he says, "that if you hurt my brother, I don't care if you're invulnerable, I will cut your balls off."

There are very few people who can threaten Captain America and make it not sound like a joke. Ron Parker is one of them. 

"If I hurt your brother, that will be entirely fair." 

He debates saying 'I'm glad he has someone looking out for him' and then decides that it sounds patronizing. 

"Good."

He furls his wings and the change that comes over him is remarkable. He's still large, but it's a friendly large, large the way the platonic ideal of a dad is large, the sort of large that will give you hugs and toss you in the air while you giggle and listen with great attention to every problem you might have.

"...how."

"How what?" 

"How did you get him to stop making terrible choices literally all the time?"

"I have no idea and I'm probably at least as confused about it as you." 

"Chris literally does not do things he does not want to do. You can't reason with him. I have been trying and what I could accomplish was 'don't inject drugs' and 'if you get an STI test I'll buy you ice cream.'" He sighs. "And now he has apparently decided the thing he wants to do is 'make Captain America happy.'"

"Honestly, I'm just glad he asked someone what would make me happy instead of trying to guess. — yesterday he showed up here in a dress and makeup and thought that would make me want to sleep with him, I expect that if he'd tried to guess we'd be having a very different conversation." 

"If I threatened every man twice my brother's age who fucked him I'd never have time for anything else."

"I imagine you might threaten somebody if he started being even more disastrous than usual in an attempt to impress them!" 

"That's true. If he went out at night fighting crime or something I would have problems." 

"I do know a teenager who fights supervillains at night and he says he does alright but I would not recommend it as a life choice, no." 

"Well, I guess if it's good for him," Ron says dubiously. "But Chris's powers aren't very useful for combat except in specialized situations, if he wanted to join the X-Men or the Brotherhood of Mutants or something I would have fewer objections."
