In one of the zoom-ins you can see that Stryker’s son, Jason Stryker, the illusionist in the wheel chair, had a pierced ear.
Now I know this is probably just the actor having one, but I personally find it such a tragic character note. With a military father like Stryker, a pierced ear would represent a period of rebellion and freedom.
Eventually, Jason was dragged home from Charles’s care. Stryker doesn’t tell us what he and his wife did to their son, but something drove him to torture his mother with illusions until she killed herself. Stryker eventually broke his son’s body and mind and turned him into a weapon, disassociating him as little more than a weapon, not his child at all. Stryker declares that his son “is dead.”
We only get little glimpses of the horror that was Jason’s life, but that piercing to me gives one of the most subtle and heartbreaking glimpses of who he was before his father destroyed him.
