Hmm....

Didn't we initially plan something similar during The Two Towers? When she falls with Aragorn over the cliff? If she falls there, Legolas would realize the feeling that he has harbored for her. Let alone, kiss her for the first time when he finds her alive. 

I guess, at this point, she and Saeril would be only of the more-stronger individuals in the Fellowship :) In terms of power.
