to GodWilling in 817 It may be one another girl in his room we do not had a good look at the head.
you may right it may be Kanti in the wrong color skin
That panel in 817 is so similar to the last panel of 816, only with a window frame drawn over it, that I believe it to be precisely that. And it isn't only Kanti who is somewhat lighter in that panel - Vik is too.
I think the Sequence gose (and That's what he gets for Trying to take Amy from ....) (NO) Adrian fall into the plane
If Vik had said something like, "What?! No! It can't be!", then I could just about accept that. But it still wouldn't work as a piece of storytelling. The plane isn't revealed to us until half a page later. And we don't see Vik's reaction. (If there had been a "No!" speech bubble coming up from the ground in the next page then that might have swung it.)
