At one o'clock in the morning, Jack climbed in through the window of Jesslyn Derei's bedroom.
Jesslyn Derei poked her head out the window, saw that no one noticed, quickly locked the window, turned around, and asked Jack, "Any clues?"
"Yes!" Jack nodded. "These past days, I've been following Brother Jayden, and discovered he went to an Underground Research Institute. Martina Autumn also mentioned that she knew a doctor who conducted underground human body research. I think Brother Jayden miraculously survived because of treatments there."
"Did you meet that doctor?" Stella asked.
"The place is heavily guarded. After Brother Jayden entered, even more guards were posted outside. Fearing that I might alert them, I didn't go in; I thought I'd first come back to discuss with you."
Jesslyn Derei's face showed a relieved smile, "As long as we can find that doctor, he can prove Brother Ethan's amnesia, and also confirm Brother Ethan's identity."
