At that moment, upon seeing Lisa's message, Oliver's lips curved slightly into a small, unreadable smile. Deep down in his heart, he felt a quiet satisfaction. 'Yes... that's exactly what I wanted,' he thought.
Before they had even stepped into that building earlier, he had already sent a coded message to Lisa.
He knew it was too risky to tell Cora. At least, not yet. She didn't need to know the extent of what he was capable of. Not now. Not with everything else already spinning around them. But at the same time, he couldn't just sit back and allow people to come at them like that not without consequences.
So even if Cora didn't know, Lisa was already handling it on his behalf. And now, with that message, she had confirmed everything he needed to hear.
That was all Oliver needed. By the time they returned from their trip, he would have answers.
Who sent her, who she was working for, what their motives were, all of it. No more guessing.
