Reaching out, he tentatively took Gaby's hand, hoping that she wouldn't pull away from him. He hated that telling her this had put all sorts of doubts into her mind, which was why he'd never wanted to tell her at all. But, Solo had been right. Illya could not have kept this secret from her or it would have eaten him alive eventually.
"Solo and I were still trying to figure out own selves out before even involving you," Illya said. "I knew I loved you... I have known that for months. With him, I was still unsure. I decided that with him it is not like it is with you."
It was completely different. He had enjoyed his time with Solo, but it wasn't like when he was with Gaby. She made him feel like nothing and no one else in the world mattered.
