I am guessing the rift between worlds only sealed because Najma was the last of the full-blooded Djinn still on Earth? I can't think of any other reason for it. Also, what exactly did she give to Kamran? Just new powers or something more sinister that will turn him into the villain for episode 6 and beyond? Also, are Najma and that other Djinn truly dead or did they just lose their physical Earth bodies, while there spirits made it back home?
I also still want to know exactly what the bangle does. Would it do anything for Kamala's brother or for Kamran or will it only work on female descendants of human-Djinn unions? Did it not work for Kamala's mother or grandmother for some reason, because I can't think of any reason Sana would not have worn it as she got older, like did they not have something just right in their genetics for powers to be activated?
Also, am I just remembering wrong or isn't their another matching bangle out there somewhere?
