I'm so confusing through the hole season 4. I was expecting those children could be more adult likes instead even those parents are acting like " wtf are you doing?!?!" Love and concerned should be more communication not like these hole season, everyone just being so themselves even they've been through all of these. Wasting 4 years and learn nothing. To be honest these passed away characters are wasted. Their death didn't teach the living anything then why bother to be dead?
