Wanda, Clint and Bruce land with the jet.
"Welcome to Budapest people" Clint mumbled, while walking out of the jet with Wanda. "I will communicate with you tso through the earpieces!" Bruce shouted
Wanda was walking to the coordinates of the woman she was looking for. "She should be right around the corner" Bruce stated.
Wanda walked around the corner and there she was. A redhead, her Daewoo precision industries K5 gun aimed at Wandas head. "I'm coming in peace" Wanda told the sligtly taller woman. "I'm not." The woman mumbles with a thick accent, as she starts shooting Wanda with the K5. Wanda holds them in the air with her powers. "You wanna do it like this? Mkay."
Wanda pulls the gun out of the womans hands with her powers and starts attacking. The woman pulls out a p-96 pistol and shoots Wandas arm.
After a while Wanda injects the woman and the russian collapses. Just then Clint comes around the corner. "Jesus what happened here" "what do you think dipshit. Carry her to the jet. I gave her the serum, she will be a little concerned when she wakes up but not dangerous.
