“After he died, they denied responsibility,” Santiago continued. “Said my dad broke safety protocols. They took his pension. Evicted us. My mom, who had been a teacher, had to quit to take care of me.”

“And now she scrubs toilets,” Leonardo said quietly—all mockery gone.

“Now she scrubs toilets for men who refuse to see her,” Santiago confirmed. “Men who never asked her name, never cared she was raising me alone while working three jobs, never knew she once taught literature.”

The picture shifted. Elena was no longer “the cleaning lady,” but a whole human being crushed by the system they profited from.

“My dad taught me everything about safes,” Santiago said, refocusing on the vault. “We spent hours taking apart locks, studying algorithms. That was our time together.”

He rested both hands on the panel.

“This model? I know it. My dad installed three before he died. He showed me exactly how they work.”

“Then open it,” Mateo challenged—swagger gone.

Santiago shook his head.

“I’m not going to open your safe, Mr. Sandoval.”

“Why not?” Gabriel demanded.

“Because if I open it, you’ll say I got lucky or cheated, or you’ll move the goalposts like rich people always do,” Santiago replied. “But there’s something better I can do.”

He looked directly at Mateo.

“I can tell you your code.”

Complete silence. They could hear the air conditioning hum.

“That’s impossible,” Mateo whispered. “No one knows that code but me. I never wrote it down.”

“Your code is 1-7-8-4-7,” Santiago said casually.

Mateo staggered back, nearly losing balance. The numbers were exact.

“How?”

“Every Swistech safe ships with a factory master code that should be changed immediately,” Santiago explained. “My dad discovered about 73% of clients never change it. They just stack security on top, but the original weak spot stays.”

He pointed to a tiny metal plate near the base.

“The master code is always the production serial reversed, with the last digit multiplied by three. The final code uses the last two digits of that result.”

He read the serial, reversed it, did the math out loud. The logic was so precise, so specific, it couldn’t be a bluff.

Mateo dropped into his chair like the air had gone out of him.

For years he’d bragged about his bulletproof safe. An 11-year-old had just shown it was an expensive toy with a human flaw.

“Wait, there’s more,” Santiago said, walking closer.

“More?” Mateo asked hollowly.
