THE DOCTOR IS IN! Within the offices, in session for one of the patients of Stephen Strange Ph.D Psychology as show by the placard on the desk.
Dr. Stephen Strange (using both real and superhero name), in typical therapist pose with his hand resting on the side of his face, starts the session off: "Robert, did it happen again?"

The patient, Robert looking slightly disheveled, and obviously going through something- I have found out that the Robert here, is none other than Robert Reynolds a.k.a. Sentry in his only appearance throughout the story.
Robert states : " Yes. I was with my boy." It goes into visions of Robert, and child at the playground and something bad is coming.
