Ah, now that I read the page in more detail, abuser anon is clever. He was able to hide the hatless Marisa's braid in the big-Reimu's own hair tufts. That's some pretty nimble fingers, considering that Marisa was jammed up into Reimu's hair.
Anyway, looks like Marisa in those first two panels is going overboard trying to prove it's her, and giving the braid to Reimu was a very nice touch. Now to wait 3 weeks to see what happens next...
