User blog:Merlin artist/Balinor's in the finale?!?!?!?

It's been confirmed on a trusted site (RadioTimes) that John Lynch is back playing Balinor in The Diamond of the Day part 1: http://www.radiotimes.com/episode/tdbq6/merlin--the-diamond-of-the-day---part-one

He's listed as the 3rd one down after Merlin and Arthur, this suggests that he is going to be important in the episode.

So, how is Balinor incorporated into the episode??????

I think it will either be loads of flashbacks, Merlin kind of goes off somewhere and has a vision of him or something, or Balinor comes to Merin as a ghost/spirit for advice and Merlin gets to him using the Horn of Cathba from The Death Song of Uther Pendragon.

What are your thoughts?????????
