I'm sure we have a few martial artists here. Maybe they can check over something for me. Does anything in the following passage scream "fundamentally nonsensical"?
Medea experienced a moment of heightened awareness, seeing next second stretch out before her as Sigurd telescoped the sweep kick. Stepping into and under the kick, she caught his counter-balancing arm and pulled, using the precious moment to pull him off balance and onto her hip. The side levitation throw went smoothly. As he flew, he instinctively tried to spin out of landing on his back. She helped instead of fighting it, and dived after. He hit the mat spread-eagled face down, and she landed across his back a fraction later. In a moment his left arm was scissored between her thighs and calves, as her arms locked his right in Ude Garami. She levered his elbow off the mat and dislocated it before he could think about groundwork.
She waited for the scream to end. “Submit, lover mine?”
“Nggghhh. Submit. Call the ship any damn thing you want.”
“Thanks, dear.”
Sigurd staggered off sweating to the autodoc, and Medea went to see the yardmaster. The “Long Serpent” it was, then.
