Thanks for the A2A.
First, Dolores (in the host-Hale disguise body), carries five control units (“pearls”) in her purse while escaping. I think one of those is for Teddy, because he is the love of her life.
However, she has already learned her lesson about him. In Wyatt mode, Dolores tried to control Teddy, and make him cruel and violent. Which was against his nature, since, as MIB said, he is here to be the loser. That was why Teddy shot himself in the head.
A main theme of WestWorld is about making individual choices. Even when someone else disagrees.
Dolores now knows that, she needs to allow/enable Teddy to make his own choices. And will try to set him free on the mainland.
