Rita now only had her right leg free, while Lee was almost totally immobilized. He tried to get away but his right hand was no match for both of hers and he didn't have enough leverage to free his left. He was now under her control.

Rita knew that the foot choke wouldn't finish her opponent off quickly but with his current position he would almost certainly have to give up eventually. On the other hand, she could transition into another submission that would have him tapping out faster.
