"Professor Charles, I have some bad news."
In an office at Xavier's School for Gifted Youngsters, Schiller held a medical file, frowning with a grave expression. "Yesterday, I conducted another follow-up examination on Doctor Banner. The condition of the personality inside him is not encouraging."
"What happened?" Charles asked with considerable concern.
"Do you remember? We guided Doctor Banner in building his own Mind Palace, but Doctor Banner is a scholar. The mental architecture he envisioned was... rather dull and tedious."
"In his mental world, he built a city of steel, something like Tony's. But that sort of environment can easily provoke that unstable personality."
Schiller sighed and looked down at the file. "Last night, I visited his mental world. The personality called Hulk lived in a room inside a skyscraper, surrounded by robots. It was practically like being locked in a cage."
"Previously, we suggested that he treat Hulk as he would a child, so Doctor Banner specifically built him a playground. But perhaps Doctor Banner had never been to a playground before. The toys there were all mechanical parts and rockets, completely unsuitable for helping Hulk relieve stress."
"As a result, Hulk, trapped in that mechanical prison, has worsened again. Recently, he has begun destroying buildings in the city. Last night, I did my best to soothe him, but that is not a long-term solution."
Charles shook his head and sighed as well. "An adult's personality cannot easily be changed. No matter how much outside influence is applied, in the end, they must rely on their own motivation to change."
"Clearly, Banner is unwilling to change his current lifestyle. He does not want to spend large amounts of time playing or visiting amusement parks. He has devoted his entire life to scientific research."
"Yes, exactly." Schiller affirmed this.
