So well, she sent me her energy bottle, and I don't have any way to refund her(Will, as soon as I get more money) and now she can't access anymore the site (it said an error processed in the server or something like that.) 

Hurr... I don't know what to do with her, and she's telling me to send her the bottle back but I can't because I used it (I thought that it was someone else)

Her name is "Sherlock" .

We moved Sherlock to the next tutorial step.

It's quite a stange action to give away a unique tutorial item when the instructions directly say to use it.

Yes. Well, I'll send a potion back asap if you want. Next time she gets a problem, I won't help her xD
