I took it as she went back too When the girls were singing to her, she was flashing back, he said "sorry"... and she had this look on her face like she gave in and that was the end of the flashbacks. Then she looked guilty when the girls were hugging her when they were done. They left it up to interpretation I guess.

I guess I didn't find Kurt's backup outfit and dancers so out of place. He did say, "Just in case..." (or something like that) And they always have a band ready to go wherever they are all the time. lol.
