good post..very nice observations!
1) she is visible? & my add "is she touchable" and her physical form.
- i think she is visible to only those whom she want to be visible to.. just like spirits. they appear to only some ppl..and ppl with certain characteristics can see, feel, talk to them.
- i think she can take any physical form.
2) Old guy
- i think he is "real" person. i don't think he knows total truth, but he may have past records as in "jungle ki kahania" he might have heard things.. i like how Romaila has made the connect to PYEK story
