Strange patients
Right before his impending car crash that would turn the neurologist into the Sorcerer Supreme we know and love, doctor Strange is getting a few potential patients pitched to him.
One of those patients in particular rings a bell and has viewers speculating. The person in question is referred to as an Air Force colonel with a crushed spine, caused by experimental armor. Many embraced the idea that this could be Rhodey, seeing how he was recovering from a spinal injury following the events depicted in Captain America: Civil War.
However, early on in the film, we see Strange a few years in the past compared to other Marvel films, with the very ending of the movie being back in line with the Marvel Cinematic Universe timeline. His last days as a doctor run somewhat parallel with Iron Man 2, meaning the injured soldier could very well be the poor man who got his spine twisted wearing one of Justin Hammer’s suits as seen in the courtroom scene in Iron Man 2.
