That footage is great! Was kind of hoping Emily Van Camp might turn out to be Carol Danvers, but SDCC squashed that dream.
What if Peggy Carter was working for SHIELD in the '50s and one of her co-workers was a guy named Lawson who was really a Kree spy. He eventually dies transferring his powers to Peggy and she becomes Ms. Marvel/Capt. Marvel/Warbird!
OK, just trying to keep Hayley in the MCU and bring her into present day. That woman is fantastic!
