As far as you know.

A week later you're pretty confident no-one has noticed your secret training and your skills are improving steadily. You find that you pick up skills with the dagger and barehanded the quickest, probably because of your muay thay training and hunting experience. This pleases you as you hope using a dagger in the duel is likely to make Khal Fonno underestimate you. You don't think you're ready yet but you plan to challenge him within two weeks from now.

If you manage to take Fonno's title of Khal you're quite sure the people will accept it as the other warriors respect you, the slaves seem to fear you less than the other warriors and the women seem comfortable around you. One of the latter worries you. Fonno's daughter Thirli has been uncharacteristically kind to you the last two days and she is known to be as conniving as her father is aggressive. With what you know of her you think that she'd make a great tactician if the dothraki respected their women enough to give her a job like that.

As you don't think Thirli is a bad person, you don't mind her persence. She's cunning but so are you, and if rumors are anything to go by she uses her cunning more to prevent bad thing from happening to herself and others (but mostly herself) than to do bad things herself. Unbeknownst to you she spotted your secret training and decided to investigate, soon figuring out your plan and decided to support you as she knows you would likely treat her and the other women better than her father does. She doesn't give any sign of knowing of your plan and lets you think she treats you well because she likes you, preferring to help you in secret.
