"Thank you!"

"Our mom is the best mom."

"I would agree, but I can feel my own mother rising from the grave to shake her head in disappointment," Barry jokes. 

"So I'll have to say second-best." 

He beams at Carita. 

"A title I'm proud to hold, under the circumstances."

Dinner proceeds, and is enjoyed by all. 

Barry arrived vaguely expecting an interrogation of some sort from the twins' mother, but has pretty much forgotten to worry about that.

After dinner, she sends the boys to clear the dishes and turns to Barry.

"I don't mean to hold you to account for your teammates' actions, but I heard something about Batman being likely to spy on us?"

"...yes, he does that," Barry admits. 

At least she's not mad at him?

"There's no evidence, of course, but I'm pretty sure he knows the secret identities and weaknesses of everyone in the League - and our associates. He's all but admitted to knowing Superman's."

"Seems a little impolite of him."

"A little, yes. Especially when no-one knows his identity, or Robin's." 

Barry scratches the back of his neck. "Not sure what we can do about it, though. I can't exactly get him kicked off the League; he's far too essential..."

"Oh, I wouldn't dream of trying something like that. But I'm disappointed in his lack of respect for my children's privacy."

"What do you want to do about it, then?"

Barry's a scientist; his first instinct when faced with a problem is to look for a solution. 

"Maybe I should talk to him."

"I can pass a message on," Barry offers. 

"I'm guessing you don't really want him in your house? I might be able to get you clearance to meet him at one of our bases..." 

"You are correct that I don't really want him in my house," she agrees. "If meeting him at one of your bases doesn't work out, I suppose I can always visit Gotham."

"I'll see what I can do." 

What he can do, apparently, turns out to be arranging a private meeting with the Bat at a particular address in Gotham a week later.

Barry offers to run her there, since she doesn't have clearance to use the zeta network. 

Sure, why not.

"I did literally mean 'run'," he clarifies.

"And, well, I'm told it's a little undignified." But sure, if she's fine with the Flash bridal-carrying her across several states. 

She's perfectly fine with that!

He picks her up. The world around them is a blur for a minute or two. Then they are in Gotham. 

The address Batman gave them is a perfectly innocuous private residence, in a part of the city nice enough that the streets are safe to walk but not so nice that the modest townhouse is out of place. 

"Well, this is the place. Should I stay outside, or - "

"Oh, I don't mind either way. If you think you'd have something to contribute, you can come in."

On the one hand, Batman is scary. On the other hand, he wouldn't miss this for the world. On the other other hand, this is about his sidekicks. 

"I'm not sure if I have all that much to contribute that you can't, but if you don't mind...I think I'll come with you." 

She smiles. "I don't mind at all."

They head in. 

The inside of the house is mostly consistent with its outside. A little sparse and impersonal, perhaps - it's increasingly obvious once they're past the hallway that no-one actually lives here - but nothing that would attract unwanted attention if a neighbour happened to wander in. Nothing in plain sight, anyway. 

Batman is waiting in the living room, a dark silhouette against the light streaming in through the blinds. 

"Ms. Nelson," he greets her. "Flash." If he's surprised to see both of them, it doesn't show. 

"Batman. Thank you for meeting with me," she says. "I heard a rumour that you make a habit of learning the secret identities of everyone associated with the League, and I was wondering if you'd like to explain yourself."

...well. She doesn't waste much time, does she. 

"I do," he admits.

"For security reasons."
