When Tibby was walking in the isle she saw Bailey laying on the ground eyes closed past out.
So she called the ambulance, when they came they got her out of there, and they took her to the hospital.
It was then the next day and Bailey arrived at Tibby's doorstep, because she got something in the mail and that's when Bailey started following her.
So Tibby goes to see Bailey in the hospital, because she has leukemia. Another thing is that she had the pants sent to her from Lena still so she bringed that with her so it could help Bailey get better.
When she was talking to Bailey she wanted Bailey to keep the pants to help and save her even though they don't fit her.
It was then the next day and Tibby found out that Bailey died, so she is going to continue the video that she was doing at her work.
