Keira stood before old Mr. Sims, her voice steady but her heart pounding. She had come to confront him with the truth, and there was no turning back. "I know that Barry Brandt isn't a traitor," she said, her words cutting through the air like a blade. "And I also know you're not a spy."
Old Mr. Sims paused, his weathered face frozen for a moment before he let out a low chuckle. "I don't know what you're talking about," he said, but his eyes betrayed a flicker of uncertainty.
Keira stepped closer, her gaze unwavering. "Everyone says Professor Brandt betrayed his country. They say he'll never return. But only a handful of people know the truth: he's been nurturing talent for the nation from abroad, and one day he will come home. That day might be far away, or it could be tomorrow."
Old Mr. Sims's expression shifted like a storm cloud. Suspicion and shock rippled across his face. "Who are you? How do you know these things?"
"It doesn't matter how I know," Keira replied softly. "What matters is this... I'm sorry for what you've endured."
Silence fell between them, heavy and thick. Old Mr. Sims clenched his jaw, fighting an internal battle. Keira pressed on, her voice gentle but relentless. "I understand your role perfectly. You're playing a part in his plan. If your act isn't convincing enough, Country M might catch on, and his return would become even more dangerous. You had no choice but to carry this blame."
Old Mr. Sims shook his head, but his voice cracked. "I really don't know what you're talking about. If all this were true, the higher-ups wouldn't have imprisoned me..."
Keira sighed. He would never admit anything without more proof. So she revealed what Lewis had whispered to her at the mention of Barry Brandt's name. "A friend told me he met Professor Brandt. Though he appears to be a traitor, his heart belongs to his country. When he recruits students abroad, he might say they won't return—but privately, he's selective. His students sign an agreement to come home."
Old Mr. Sims's brow furrowed deeply. Keira delivered the final blow. "That friend is my husband, Lewis."
The old man's facade crumbled. He knew he could no longer hide. His eyes bored into Keira's. "Can I trust you?"
"Yes," she said simply.
"Even if I don't trust you, I must, mustn't I?" He spoke gravely, his voice heavy with years of secrecy. "As a member of the Freeman Sect, you are patriotic at heart. So I beg you—please do not let this out."
He continued, his voice trembling with conviction. "Barry Brandt's overseas research is critical for our country's development. We are at a pivotal juncture. Once this research is complete, he can lead his students home! So at this stage, I must be a spy. I can only be a spy!"
Keira's heart ached. "How long will this critical juncture last?"
Taken aback, old Mr. Sims hesitated. "Not long."
"How soon is 'not long'?"
He clenched his jaw, staying silent. Keira turned to face him fully. "I am a scientist too. I understand that 'very soon' could mean two years, five years, or even longer. Every scientific breakthrough reaches its toughest phase just before success. You can be imprisoned for a week, a month... but what if it's ten years?"
Old Mr. Sims laughed, a hollow sound. "Then it's ten years."
"Your imprisonment. Your son's house arrest. Your granddaughter struggling against accusations of being a traitor's child. Don't you care at all?"
His eyes drifted to the distance, as if seeing the past. "Some of what I told Holly earlier was true. Years ago, when her grandmother fell gravely ill, only Country M could treat her—but they demanded a hundred million. After she passed away, I was devastated." He turned back to Keira, his gaze fierce. "It hurt me to see our country lagging behind in technology, especially in medical science. We've been catching up slowly, but it's not enough. We need to be at the forefront, making others plead with us, not the other way around..."
His voice grew resolute, righteous. "I don't want Holly—or any Creran—to be at the mercy of foreign countries when they're ill, subjected to their whims and harsh conditions."
Keira looked at the eighty-year-old man before her—gray-haired, worn, but unbroken. All of this was for the prosperity of Crera. She remembered her ancestors' painful history, their words echoing: "I have endured these hardships so my descendants won't have to suffer."
Tears welled up in Keira's eyes. "So you never stepped down because this situation needed a scapegoat, and you didn't want Brian to become that scapegoat? You sacrificed yourself to protect him?"
Old Mr. Sims smiled. "After all, I am his elder. Now that I've been captured, he can take over the Special Division with a clean slate."
Keira was deeply moved—shocked, even. "You sacrificed yourself for everyone's benefit... but what about Uncle Sims? What about Holly? They are your son and granddaughter!"
He laughed again, but this time there was sorrow in it. "There always have to be sacrifices. I believe that when the day comes for my innocence to be proven, my son and Holly will forgive me. It will be soon, very soon..."
A single tear rolled down his cheek as he looked at Keira. "You don't need to help Holly. Her surname is Sims. And the Sims family creed is patriotism—sacrificing personal matters for the nation. This is her duty as well."
Keira stood speechless, her heart heavy with admiration and sorrow. This man, branded a traitor for years, was in fact a hero bearing an invisible cross for his country.

**Reader’s Impressions & Star Rating**
What a powerful chapter. I felt every ounce of pain and pride in old Mr. Sims's words. He is one of those silent pillars that hold up a nation, asking nothing in return but time and trust. The way Keira unravels the truth is both gentle and relentless, and I love how she respects his sacrifice even as she grieves for Holly and her family. This chapter made me cry—not from sadness, but from the sheer weight of the love these characters have for their country.
⭐️⭐️⭐️⭐️⭐️ Rating: 4.9 / 5 Stars
**Next Chapter Prediction**
Now that Keira knows the full truth, I believe she will have to make a difficult choice: should she expose the secret to help Holly clear her family's name, or must she keep silent to protect Barry Brandt's mission and the bigger plan? Old Mr. Sims asked her to say nothing. But Holly deserves the truth. The next chapter might see Keira torn between justice for her friend and loyalty to the country she loves.
