I have the crossovers on this worked out, I'm just going to put them in as I post the parts for the surprise.

Seeing his target, a beautiful red headed woman in a designer gown, across the banquet hall, he quickly crossed, pausing only to grab a flute of champagne. "My dear Pepper!" he exclaimed as he came closer to the her and her companion, a younger woman with dark curly hair.
"Eyal! How wonderful to see you again," Pepper grinned in reply. "Let me introduce my dear friend, Darcy Lewis. Darcy, this is Eyal Lavine."
Bowing before the young woman, he grinned. "Any dear friend of Pepper's is a dear friend of mine." Standing up, he continued. "How did you two lovely ladies happen to meet?"
Ms. Lewis grinned. "She came to my labs to apologize for the tornado that was Tony Stark. We then bonded over shoes and good coffee."
A scientist at Stark Industries? Interesting. A good contact to cultivate. After chatting with the two some more, he decided it was enough for a first meeting and said his goodbyes.
Hours later, as the party started to wind down, and feeling accomplished for his night's schmoozing, he decided to retreat to his hotel room.
Walking down a hallway towards the elevator, he was suddenly attacked and thrown to the ground. Before he could get up, a blur impacted with his attacker.
He watched in shock as Ms. Lewis from the party proceeded to calmly attack and finally kill his non-human attacker.
"Are you…" the young woman paused as she saw it was him. "Mr. Lavine. Are you okay?"
Pulling himself up and dusting his suit off, he nodded. "I’m fine, Ms. Lewis. And, may I say, you did quite well against that demon."
"You know about demons?" she said with a sigh. "That makes this easier."
Definitely more than a scientist. A slayer perhaps? She definitely needed to become an asset.
"Let me make a phone call to take care of this," the young lady said with a small smile as she pulled a cellphone from her purse. A few moments later, she started to talk and the smile dropped from her face. "Alicia? Didn't I tell you and Liz to clean up around the Savoy? I remember asking you two to patrol here."
More than one slayer? That would be a coup. A large coup.
"Considering I had to save a party goer from a very large demon? I'd say you didn't patrol hard enough." Rolling her eyes, Ms. Lewis continued. "No, I'm not getting Captain America to come down and help 'mop up'. He's off saving the world. No, I'm not telling you where, that's classified. Just get down here and help me clean this up."
Wait. She knows Captain America. And, where he currently is. Damn it. She's SHIELD. And, she must be talking to other SHIELD agents. There goes my asset coup.
"I apologize for your distress tonight," Ms. Lewis said as she smiled winsomely at him. "I hope this incident doesn't adversely affect your evening."
"I'll be fine," he replied with a smile and small bow. "Have a good evening."
"You too, Mr. Lavine!" she called out as he strode away.
For those not familiar with Covert Affairs, Eyal Lavine is a Mossad agent played by Oded Fehr.
