My french is super rusty but the author of the article appears pose the question that in ESB Yoda may not have meant Leia - in reference to 'there is another' and suggests it may be the apprentice.
The rest of it mentions he has some memories of his past.
Something about a half million storm troopers on Kamino - I think it just says you fight your way out of Kamino???
And a mention that the arena fight takes place on Cato Neiomoda (sp).
And it looks like a classic game device - the clone apprentice is searching for Juno. I guess he remembers her. And he teams up with General Kota to find her, but he needs Maarek to fight for the rebels.
Take nothing I said as a direct translation - my french is really ruster.
