I see 2 besides BK who are missing from photo #2 and photo #3. The partially cut-off person sitting to BK's left in denim/light blue doesn't seem to be in the other photos. Neither does the woman sitting a few rows behind BK who is wearing a white cold shoulder top.Not sure if it means anything but I notice 2 people missing from the second photo. MOO
I don't think the photo with BK is fake. It appears to have been published in summer 2018 by NCC.
