Who do you think is the leader of Totally Spies?

Putting Jerry aside, who do you think is the leader of Totally Spies? Usually, it's always down between Sam and Clover. In my personal opinion, I think its Clover. I mean sure Sam is smart which is her et in the group Clover brings the group together, she's a good driver (it was stated in the 1st season that Sam and Alex were bad drivers), is the one who is almost always in the middle and etc. I mean remember Jerry's old spy group? The Blonde girl was the leader and its obvious she was portraying Clover. Its the same with Mandy and her group! Anyways, just wanna know what you think. THANKS!
