Here the sisters need help, they haven't come across this kinda demon before, and to find out it was 1 who "started" the whole family of witches and she had already dealt with this demon before well why not get her?
Of course we see more of Prues "evil bosses", as they are the ones who tricked Prue into releasing this demon in the first place. Poor Andy though, knowing somethings up with Prue, even suspecting it, but still...
The only thing is, Melinda should be younger, poss a bit younger than Phoebe (about 23), to go with her age when she died, Prue is what 28, Melinda looks about the same maybe a bit older.
Time line, no change other than that demon is gone, poss for good as Melinda "took" him with her (locket) when she left.
