Of course not....It's kind of obvious.....Octavia's new love interest is going to be Ilian. They have this chemistry going on between them. The directors probably made Octavia run off into the woods with Ilian following behind because they are going to develop some sort of a relationship. I know Octavia is still not over Lincoln's death, but at least Ilian will come to like Octavia, if not the other way around. So therefore, Ilian is not going to die anytime soon. He's sort of an important character to the plot.
