She reads emotions*, but training from an experienced mind mage (none still exist) can allow her to read toughts as well. As for the 'Sleeper Tanks', I would remind you that they didn't achive their main purpose, it was the true Stasis that did that. All they did for Athena, an Adept who can conjure food and implant good dreams can do. Yes, she'll be my hero, and yes, she can read supernatural creatures just fine if they're not conciously protecting themselves. However, a sufficiently powerful and controlled supernatural creature can change his or her aura, and thus the emotion it expresses. With Eubarates or Lorda, she may just feel the emotions associated with Creation Mana. A lot of Creation mana.
*That would be the purview of Spirit Magic, but she was exposed to that as well.
