The most important note Aria makes from this: Clearly some of the ingredients that make potions human-specific also increase the intensity. After all, it was only supposed to cause a minor infatuation... Either that, or everyone is sluttier than she predicted. It might be a bit of both. Shemhazai is a very interesting side note however: Either she's somehow immune, which shouldn't be possible, isn't human, which mean she's lying to everyone, or has her own water supply, which means she doesn't trust the bandits... correctly, considering Aria's experiment. She'll try to get closer to Shemhazai to see which one it is, as it's a bit too early to make a confrontation out of this.
As for the experiment itself, it's a success... however, Aria is concerned that the increased power of the potion compared to her calculations may encourage Tristan to steal from her in the future. She was originally intending to try and deter blame from her pawn, maybe by blaming the goblin, but now she might need to leave him to the wolves once they sober up...
Assuming they're even smart enough to realize they've been drugged.
For her own cover story, she's acting shy whenever the boys interact with her and is mostly shutting herself in her lab. If she has to fake a blush and run off like a shitty romance character one more time she'll spike the boy's food with laxatives for the next week.
