After Samantha and Ivy arrived, they were greeted by a young lady. She was not the one that was there the previous time.
They followed the same procedures and they were taken to the testing area. There, Ivy underwent the test in the machine, just like the one that Jack and the rest of the group had used for testing.
One star appeared before the second star followed. Samantha was not expecting that there was going to be a third star, considering that, Ivy had just taken the serum. So, unless she trained, there was no way that she was going to be able to reach the third star of the ordinary human level.
After a few seconds, the one that was in charge of the test took a step forward and pressed a series of buttons on the machine. After that, Ivy was taken out of the machine.
