I know it's a fictional tv show but for such a small town an awful lot of drama/tragedy seems to happen:
Jack getting shot (I know that was the end of S2)
Doc getting diagnosed with whatever it was (can't remember the name)
Lilly dying - also what was with that? I know she had terminal cancer but she seemed fine that day, went for a nap and never woke up
Brie's miscarriage
Hope's accident
Preacher getting drugged
Mel's ongoing trauma/sadness from her husband dying and losing her baby and then the storyline with her getting pregnant at the end, how did that happen so quickly
Also as other's have said - what is up with Charmaine's non existent bump, she just looked like me after eating dinner. She must surely be ready to give birth anytime now. I'm kind of confused about the timeline for this series as a lot of big events happened but the twin baby bump hasn't grown
And one last comment - Jack & Mel both just seemed so miserable the whole series. I know they had a lot going on but for a newish couple supposedly in love you would think they would at least smile or laugh every so often.
