Ah you're right, in that case he is only King Leopold first wife's brother so he doesn't really have a claim to the throne, unless Leopold was Eva's consort (though in his case Leopold would only be prince consort, not king so this theory fails). He could be a threat to Regina's throne if he decided to help his niece and invided Regina's kingdom with his army, but I don't see that happening in OUAT.

As for timeline, on the pic we see Snow White in her bandit outfit so I guess you're right about that. I read earlier today that Ariel will start episode 6 with saving one of core characters and then will go on her own adventure so now I am even more sure it is Snow White.
