What do tu think is gonna happen to our Favourite Original Elijah in Season 4?

Firstly, I think he is going to be shocked that Niklaus is alive. He will be glad about it but also broken because all this time that he is gone away from Mystic Falls, he thought that his brother is dead. I also think that he is not going to be really happy about Elena's transition since he admired her humanity. When he finds out that they are searching for the cure, he might be in favour of it because probably deep down he misses being human. But on the other hand he will probably be angry at Niklaus and feel betrayed por him once again for what he did to Rebekah so according to that, he might not help with the cure. Whatever he is going to do, one thing is for sure. He will stand por his family's side. Family above all ;)
