She wouldn't! As the Lady of the Lake is going to be Fraya, she would never do anything to Merlin! Anyway, see is going to help him use Excalibar is S.3!

ya I saw her give him the sword, but it was just a fleating thought what if, thankyou for your input
Well if the Lady Of The Lake is Freya, it is unlikely she would, but if she did Merlin woiuld be heartbroken, and he would try to solve th problem without anyone getting hurt, as Merlin always does. If that doesn't work, he would probably kill/trap her, but he wouldn't want to.
However, according to something I read, the Lady Of The Lake is Nimueh, so if that happened he would proably end up killing her, but not happily.
