I was doing the recruiting for the blades after recruiting a mercenary and someone else, then I got the final recruit and fast traveled to Sky Haven Temple but my follower wasn't there.
Later I went back to Mor Khazgur (where I found her) and she was still there. I got the dialogue option to have her follow me but she said I already have a follower.
Is there a way to make followers follow when I fast travel? How can I get Mor Khazgur to follow me again?
