NOTE: This is a sequel to An Unexpected Request, posted elsewhere on this site. You don't *have* to have read that one for this story to make sense, but I certainly encourage you to.

Continuity note: I'm tweaking canon just a bit, such that Alex Danvers doesn't find out Jimmy is the Guardian until Kara does. She has suspicions, but Winn never confirmed them.

James Olsen didn't think being a hero - a vigilante, according to the press - would ever get old. Exhausting, maybe, he thought as he raced through the streets of National City on his motorcycle at an hour when many people were heading to bed, but not old.

For just a moment, he envied Kara Danvers her alien physiology that meant she didn't require as much sleep as he did. But he'd been experimenting with polyphasic sleep and studying techniques used by Navy SEALs and other special forces units, and, if he did say so himself, he was getting used to the odd ours the work required.

Of course James shared what he discovered with Winn, but his man in the van seemed to be having more trouble adapting than he was. James hoped Winn would adapt - he couldn't do this alone.

"Alarm." Winn's voice came through his comm. "Adams Jewelers at the corner of Binder and Swan."

"On my way," James acknowledged, and gunned the engine.

Minutes later, he skidded to a stop in front of the jewelry store.

The door stood open, and James approached cautiously. "Talk to me," he said to Winn.

"Someone cut power, at least to the video," Winn replied, anxiety edging his tone. "I got nothing."

Dammit. But there was nothing to be done for it, and when James eased his head around the door, he couldn't believe what he saw.

One man, hooded, with a bow and arrow, of all things, stood over the bodies of two security guards.

Four hours earlier….

The portal appeared just shy of six p.m. Oliver Queen was ready when it did - or, maybe not ready so much as prepared, he admitted privately - dressed in jeans, a t-shirt, and leather jacket, a duffel containing his gear within reach.

Beside him, Thea started. "That's - weirdly cool."

"Or just weird," Oliver corrected. "I'll be back soon."

"Forty-eight hours," Thea said. "Or we're coming to get you."

"I remember." He grabbed the duffel and stepped through the portal…

And into a facility that reminded him of A.R.G.U.S. headquarters, not just because of the array of weapons aimed at him.

He scanned the faces of the people holding those weapons - a black man with a careworn face and an expression caught between annoyance and anger, a white woman with auburn hair and a determined expression, and a petite Mediterranean-looking woman with a scowl that could rival his own.

The portal closed behind him before he could dive back through it, so Oliver held still. "My apologies," he said. "I think I've come to the wrong Earth -"

"Oliver!"

He recognized the voice, and even as he turned to see Kara rushing toward him, bright cape billowing behind her, he registered that the others were lowering their weapons.

Then Kara's arms were around him. "Thanks for coming."

He hugged her back, briefly. "Any time. Though I wasn't expecting a welcoming committee."

Kara pulled away and turned to the others. "See, I told you it would be him. This is Oliver Queen, also known on his Earth as Green Arrow."

The black man holstered his weapon. "I have enough headaches with aliens. I don't need dimensional travelers, too."

Oliver met the man's gaze. "I'm just here as a favor to Supergirl."

The other man grimaced and turned away. "Try not to break anything."

"That's Hank," Kara said.

"Director Henshaw," the auburn-haired woman clarified. "I'm Agent Danvers."

"My sister, Alex," Kara said. "And Detective Maggie Sawyer, NCPD."

"More of a welcome than I was expecting." Oliver shook hands with each woman in turn.

"Well," Kara said, "I saw enough of how you operate on your Earth, and Barry told me some stories. I figure you'll need some help, so here it is. Welcome to the Department of Extranormal Operations."

If Oliver had learned anything over the years, it was how to keep going through unexpected situations. He pushed his curiosity about the DEO aside for the moment. "All right. What do you know about this … Guardian?"

"Not much. He just showed up recently, and he's got lead in his mask so I can't identify him." Kara gestured toward a bank of computers. "And Alex thinks he has a partner."

"Why?" Oliver asked.

"He always seems to be one step ahead of his opponents in a fight," Alex answered. "Either he's really that good, or he has someone working with him."

"Do you have video?"

"Some," Alex answered.

"Then let's take a look."
