ONCE UPON A TIME- EMMA SACRIFICES HOOK

Season 5 half is going to end soon in december , and we have seen emma and hook past scenes , where they are sharing love , emma is trying not be dark , but its not always easy to control your darkenss inside you , emma recently did something dark by taking out the heart of voilet and hurt henry's feelings even if it was for the best to free merlin from the tree , thats pretty sure that emma is going to sacrifice hook to get rid of all the darkness and save everyone , but we can't just ignore the fact that world's most evil creature is SATAN or i say devil , there was a spoiler too  about once upon a time directors casting a devil like creature and a God like creature , so its pretty clear that other half of season 5 is going to be about the underwood , may be hades will not come in season 5 or season 5 is going to be the last , in super natural when devil was introduced then that was the last season , so may be same will happen on once upon a time .

ONCE UPON A TIME ''HOW HADES WILL FIT IN STORYLINE''

we all have seen the bad blood relationship between captain hook and dark one , hook is so curious and he wants to get the revenge from dark one so badly , but the reason for revenge is that simple ? because of what dark one did with his love? or there is some other reason behind all of that , My theory about hook is that , he is betraying everyone  he is working for hades from the start , when his brother died because of never land incident , he went to a mysterious mythological place throw magical portal to find hades , because hades is God of death , which can revive people , so he went there to help his brother , Hades has no power left to do that , so he wanted that dagger and sword , so he sent hook on a mission to get that sword attached with dagger , in end of the season when Merlin will destroy all the darkness from Emma then hook will attach that dagger with sword , then a magical portal will open to a mythological place where hades is waiting for hook , and a new quest will begin , for heroes to save Hercules and everyone from hades.
