Was Gaia nervous about being in this part of the city? Yes, but she didn't let it show. She knew better than to show fear or nerves of any sort. So she had the appearance of a woman who knew where she was going and what she was doing. And of course she'd been unsure of meeting Moriarty here, but needed the drugs before she ran out. Before the withdrawal symptoms kicked in. She had been through that hell once before, and she was not going to go there again. There was also the fact Gaia was fully aware of the fact that she was completely indebted to Moriarty. Of that she had no illusions. All that needed to be determined was what exactly it would be that Moriarty would ask of her.
After he gave her the look over, Gaia took her turn to look him up and down. Very smart suit, not that she was an expert in modern fashion, but it looked good. Upon the invitation to sit down, Gaia took a seat in one of the chairs. Oh she liked the detail of him kissing her hand, the little brush against her arm. Now she didn't exactly have anything specific on her mind when he gave her that little look and touch to the arm. But if he wanted it, she'd give it. After all, she knew whatever he asked of her, she needed to give in order to keep her drugs coming.
"No, I do not. I am open." At least for this meeting she had an excellent grasp on the English language. Of course, there were still times where she was left clueless by what someone said, but she had come a long way in learning the language in the little time she had been here. Angel was a good teacher, and she also spent a lot of time reading and learning it on her own. Gaia was far more intelligent than most people knew. If they knew about her drug use, they would probably only see that side of her, not thinking she had a cunning mind underneath. She wasn't sure just yet if Moriarty knew that or not. She was not putting up a front with him, she knew better than to pretend she was something she wasn't in this moment.
Was she aware that there was a woman here that looked much like she did? Yes. Irene had so excellently mistaken her for Helena once. Did Gaia know any details about Helena aside from what she'd seen her post on the boards? Not exactly. She had read over some of the boards, but while she had an interest in Helena, she had yet to really see anything she could get ahold of and use. Not to her own advantage anyway.
