Ok heres my take on Zach and Reese and that wierd kiss. I went back and watched it again and I saw him hug her and kiss her cheek. When he was hugging her it looked like he was nuzzling her neck but it was just him hugging her harder. Does that make any sense since? I don't think he was nuzzling her neck it was just a strong hug.
As for David and Krystal, he was drugging her so she would feel relaxed only when she was with him ...so she would keep coming back to him. He put it in the warm milk so that she would think it was the milk that was doing the relaxing.
I think he wants to get her hooked on them so she can't stop him from taking lil Adam away from them.
I have RSD...but it doesn't have me!!!!
