There are many differences between Carl and Garten, but the most obvious one is that Carl is not swayed by emotions.
"The Sisterhood of Duren will split up into groups of three. Assist Master Jaren and disperse his curse. The Laurel Corps will advance in formation and block the approaching eyeballs."
Carl is not the type of person who wastes time rambling just because he has the upper hand or gives his opponent a chance to turn the tables. Words are unnecessary now. All that remains is to kill Garten.
The Sisterhood of Duren waited for Lyanna's instructions despite Carl's orders.
"Let's get moving."
Because Carl specifically mentioned 'Master Jaren,' Lyanna accepted it, knowing it was the most effective tactic.
Even though the Sisterhood of Duren is a formidable force with immense power, it is still a story below the level of the Master.
It is right for Master Jaren to be the main character now.
