The only time ever he has been in love with someone was with Freya, in season 2 episode 9.
Answer 2: As Merlin is not a particularly romantic person, he doesn't really speak of his feelings as we very well know. So it is really tough to tell. We know for sure that he has been in love with Freya, but we do not know if he still has those feelings for her, as he has not said anything about it. 18:19, September 30, 2012 (UTC)
