ok ok where to begin again aside from the whole demons and loving thing seems to have been dropped but that is ok
lets address the issues at hand
1) *sighs* ok wow this one keeps coming up with piper and coop's ring in forever charmed now there is two reasons it was not done one is on show which i will say first the other is off show which i will say second 1) the on show reason is they were focused on saving the other two sisters phoebe and paige because to piper it seemed that her worst fear was coming true again and she knew she had the power in this case (coop's ring) to stop it from ever happening 2) the off show reason is that shannen doherty has full rights to all images of her to be used ever and that never expires and after breaking ties with the show she basically didn't allow the use of her images at all 3) now this is something i have said before but off screen her death was not planned but once the desire to leave came in it became her on show destiny to die no help from the cleaners who didn't need to be involved because the agents of good and evil solved it sufficently without them if that doesn't fly sorry but it is the truth
2) ahhhh the whole leo and patty thing simply put would you not find it strange that piper phoebe and prue were the first to meet him just out of the blue and they never said he was patty's whitlighter (which was sam) they just connected them through a sit in type event and that there were feelings they never got around to exploring (if they did paige would've never been born) this is not a plot hole she just knew leo making a connection to the halliwells which i think makes sense because him appearing out of the blue to just piper's gen would have been even more suspicious and made everyone think even more this guy is evil this was a clean up for not explaining it sooner and frankly i am proud of kern and company for doing it.
3) i agree the writers should watch the show so that can be educated in the mythos they are writing for.
4) i don't remember if they said his name was chris perry haliwell when he was born but baby chris was born after adult chris went home after "dying"
5) well remember in san fran it would be very difficult to truly say what is behind alot of event even ones we think are obvious it is easy to dismiss things with a logical explanation trust me irl i practice magick so i know this from personal experience
6) jh1984x it was not a feeling she tapped into with demon power it was her using a power called channeling which was an extension of the empathy though as i have said before it think it should have been seperate and there should have been consequences to her tapping them but c'est la vie
