Aeweth regards the brothel with undisguised revulsion... and a little bit of curisosity. This is, after all, her first exposure to the seedy side of life, and she's always been inquisitive. Her detached academic gaze lingers on some of the girls sitting on the couches before moving on the the decor.
To Rhesa, though, it's all old hat. She's almost too busy sticking close to Lydia, being terrified of Gwyn, and being a combination of curious and replused by the half-ogre guard to see the fresh-faced young boy fumbling at a prostitute and recall her Priest of a long, long time ago (or at least, so it seems).
It was perhaps the closest she ever came to letting her double lives collide, and (in retrospect) she has to admit that there was a certain perverse manipulation about it. Thinking about it now, she realizes that she was more like those around her then than she'd ever cared to be. She shudders a little, internally.
Her Priest (being a good little servant of Heironius) was a fervent prothletyzer, paticularly amongst the poor, the dissolute, and the morally deficient. His young, eager face showed up in brothels at a rate that would be disturbing to any potential companion of his if he hadn't been there to preach and convert. Rhesa had occasionally wondered if there was something behind his choice of venue, but had reluctantly concluded that he simply felt he was needed most where virtue was farthest.
In any case, she had decided to test her young Priest. Her ability to change her appearance was considerable, and so the Priest had no idea that the pretty young whore that was attempting to seduce him and the chaste young girl he was to eat dinner with later that evening were one and the same. In the end it turned out it was over before it began; the young Priest's virtue held firm, and Rhesa was reduced to imagining (and darkly chuckling at the thought of) her own tearful confrontation with the philanderer. She had considered, briefly, re-trying the experiment as a boy, and then realized what precisely she was considering and left for saner waters.
She is bumped out of her reverie by the appearance of T'aria, which causes her a brief start of panic, followed by several calmer emotions. She was, to her knowledge, not being hunted by the guild- she been part of a botched scheme, but she hadn't snitched, and the organization wasn't nearly draconian enough to kill everyone involved in a failure. The question is, why was she here? And does she recognize me? What if she does? Bugger, this could get messy. She considers using her magic to make her appearance a bit more convincing, but there's no way she could slip away to use it.
Rhesa's current disguise check is +5 (ranks) +3 (charisma) +2 (synergy from bluff, since I am acting "in character") and possibly, with DM discretion, +5 (minor details only- the only notable thing is her arms and legs, which are concealed from sight anyway). T'aria might get a +4 (recognizes on sight) or +6 (friends or associates) to see through it. Rhesa will have taken 10.
