According to the textbook, "In this case, you (A) and Jackie (B) no longer agree about her speed _relative_ to the speed of the light beam. She'll see the light beam pass by her at the speed of light, c, but you'll see it going only 0.1c faster than she is going."

My question is, does her rate of time slow down or her length increase, so that to her it appears that the light traveled a full 1c instead of 0.1c in a second?
And what if she shines a light back?
