Update: 22:30 Thank again to PF108
Im fairly certain the person Jin is hugging in the earlier is this female scientist in this picture. It is possible it is Sun, but I don't remember seeing Sun that day.
Thanks to our contact from the set, PF108 here is a little up.
This is a pic of shooting during 6-14. Sawyer and Kate “rescuing” Jin from the scientist. Jin is hugging one of the scientist while two scientist stand in the rear with rifles. Sawyer and Kate can be seen in front of camera.
