Hello, hi,
BRUCE BANNER. 
I looked up from the table, I heard a squeak.
"Sorry, Dr. Banner." Bucky Barnes said before he gave me a curious look, "Can I get a wrench? Mine's lost."
"Why would you need a wrench?" I asked.
"So, the kid hasn't told you? I didn't think it would work." He said, chuckling.
"What? What did you do to Peter?" I demanded.
"Nothin'. He found me...training, I could say. And he saw something I'd rather keep a secret."
"And do you need the wrench for the same 'secret'?" I asked, inquiringly. 
"You could say that," Barnes hummed.
"Actually, can I call you James? Calling you Barnes in my head is a little funny." 
Barnes- James- hummed.
"Could you show me the 'secret'?" I asked before I could stop myself.
"Fine," he said, deflated. He took something out of his jacket pocket, a small bronze figurine. He murmured something in another language and he placed it down and stepped away.
Then the figurine started growing until it was 20 feet tall.
"What the" I stopped myself from swearing.
"This is Ventura," James said pointing at the figurine, "she's a robot."
"Who made her?" I asked, gently touching the cool body of the robot.
"I did. I'm sure you have heard interns from floor 8 complaining about missing tools and equipment?" He grinned.
"You were the one who was taking it?" I asked, still breathless, seeing the robot.
"What's she made of?"
"Bronze mixed with steel."
"This is amazing, why did you not show this to Tony-"
I was cut off, "Tony Stark has enough to do, without me  ruining his day with my presence."
"Bye." I said, dumfounded.
"বিদায়" he said, giving me a two fingered salute, taking a wrench from my table.
বিদায় means bye in Bengali. Bruce lived in Kolkata (Calcutta or whatever), West Bengal, so he either knows Hindi or Bengali, I just chose Bengali. Bye, bye.
