Someone else walked closer and stood off to one side, looking up at the same building. A tall man with a goatee wearing eastern style clothing, with a red cape over his shoulders. He squinted up at the building as though trying to see the tippy top of it or imagining what it looked like during that Chitauri invasion. He made a soft hmm noise before tipping his head down and regarding Natasha.
"A huge building for a man with a huge ego," he noted in a voice that was equal parts warm and deep, and his words carefully measured for weight before being spoken. As for the building, he knew that time and circumstance had probably knocked Tony Stark down a notch or two. Sure it wasn't much, but it was still something, and probably enough for Stark to let go of a place that held too many memories.
"Oh, sorry? I forgot to introduce myself. I'm Dr. Stephen Strange. I'm working with Stark for the time being on a unique...problem."
