Sam, Bucky, Zemo
They had a name. They could remember that from the other universe they came from. In this universe, there was no guarantee the serum creator was in the same place as before. What they needed most was a location.
"Dear Selby. Rumors of my past crusade have traveled far," Zemo said, gesturing with his hands, keeping them in the open so the guards and Selby could see he was no threat. A greater threat was standing beside him. Having Bucky there meant the guards were on edge, thinking their guns would protect them. "I've heard of a name of a super-serum creator. Nagel. What I need is where I can find him."
"You were right to come to me, Baron. But mucking about with the Power Broker is going to cost you," replied Selby, looking at Sam and Bucky with an appraising eye. "What's your offer?"
"If you tell us the location, you will get him," Zemo said, patting both hands on Bucky's shoulders. At least he didn't do that chin tweak again. "Along with the words to control him."
Selby looked delighted. It would put her on the Power Broker's radar. But having the Winter Soldier meant the Power Broker could be eliminated, and she had a shot at taking her place.
"All right," Selby said, standing up. "I'll give you the bakery since you already know the baker. Buccaneer Bay. Last I heard, he's on a tugboat called Xie Xie. Near port three."
Zemo turned and looked over at Sam with a smirk like they had what they needed.
