Legolas watched and listened to Yavanna, to the point where his surprise became apparent when she took off her necklace, and placed it within his palm. Honestly, as much as he'd wanted to stay with her, he had to venture out to clear his thoughts. But for this gift to be handed to him, it was a gift for the princess to express her concern and love. "You've found great friends; great enough to be family", it was almost like a blessing that he would accept Yavanna's decision to befriend the dwarves, as well as an apology when he criticized her on her choosing of friends, back in Mirkwood. 

Having to see Tauriel approach the two, the blonde elf looked back at the girl before him. He wasn't sure if he should do this, but felt the urge to. Placing one hand on her cheek, the Prince laid a lingering kiss on her forehead. He was going to miss her, certainly. He was determined to see her green eyes once more, when they crossed paths again. "Keep a weather-eye on the horizon", he informed her, before turning around to see Tauriel ready to begin walking. Giving her one last squeeze upon her hand, he reluctantly let go, holding the girl's necklace, while following the red-haired she-elf away from the Mountain.
