She seems like a totally different girl when that guy is around. She's happy and smiling and constantly doing sexy dancing. She even has real animated discussions with him and is full of energy. But, when she's home with Alex, she acts like she's deeply depressed and barely speaks. I don't think I have ever seen her smile with Alex.
Last night, she was acting like she cared about alex and even gave him a couple of (very quick) little kisses. After a while, Alex ask her something and, when she answered him, he smiled like he was happily surprised. Then, he got up and went to the bedroom. I thought she had promised to join him or something. But, she waited in the living room until he gave up and fell asleep. Then, she went in to bed making as little sound and movement as possible so as not to wake him and immediately grabbed her big stuffed rabbit and hugged it tightly to her chest as if to protect her from him. Very, very strange.
I have my theories about what's going on, but the only thing I'm absolutely certain of is that they are not a romantic couple in any way, shape or form.
