Dollhouse going Alias?

After episode 6 of Dollhouse one might think they are going Alias.

This episode reveals some previously unknown facts. Echo plays house and meets FBI boy twice! A rapist in the Dollhouse are dealt with. And finally FBI boy gets laid. All in all a good episode. Though …

***Spoiler alert ***

Are Echo going to work together with FBI to take the Dollhouse(s) down and find out the real reason behind them (Which wouldn’t be world domination with mind controlled masses?) like in Alias?

Or it might be a ploy for something else. I hope I’m not right, it’s been done already.
