I didn't know about Lais. But i thought both concerts (Pink Martini and that tribal one) began and ended at the same time and the assumption that the girl may have seen them at the soundtuary concert might be wrong.
I don't know when she left the Martini's concert but that bathroom selfie was taken at Adriennne Arsht Center's bathroom, where Pink Martini concert took place at IMO. Bc i saw others stories from similar bathroom at that center,
so i assumed she left too late to make it to other concert.
Idk. If she really went to , i want to see more of her look, liked it so much.
