Jessica didn't particularly understand, but she took what Abra was saying at face value and it made some sense. If whatever these things were had decided to call themselves Legion, to reference that particular story, trapping them seemed better than getting them out, getting to other people. She nodded briefly, "Okay."
She got on her knees in front of Abra, back to her. "Climb on, do what you need to, I'll carry you after him when they need to move." Thankfully her wings sat close enough to her back and Abra was small enough she'd be able to settle between them fairly easily. Jessica probably wouldn't have enough range of motion to fly very well but she wasn't sure she'd have been able to anyway with the sore wing and missing feathers, and she would feel better having Abra behind her instead of in front.
