I think Merlin does need an ally, and it would be nice if it occurred in this series. Actually, we must not forget that Mordred knows Merlin has magic, and we do not know what side Mordred is on at the moment. So, to some degree, someone already knows, but it's not necessarily Merlin's ally. Another piece to remember is that the producers are telling this story in a new way from legend; mingling and intertwining the myth and legends of Camelot, redefining characters and their relationship to Arthur and Merlin. So, Mordred might very well be the one who knows this season.

 My theory: The show has gone on long enough to tell all of the pieces of the legend in the way they tell it, and there is not much more that can be told other than the journey towards Arthur's death. I think we will see a Series 6, and the finale of Series 5 will include the reveal as a cliffhanger. Ugh! That would be a long wait to see Arthur's reaction and what he does to or expects of Merlin as a result.

 Remember, the producers did not confirm nor deny a Series 6, so that tells me they are writing for one, but if BBC says no, then what they write they will make into a feature film or mini-series finale to wrap up the show and the storyline. Either way, I think we will get a reveal, but it won't happen until the finale and we won't see the reaction until a possible Series 6 if ratings justify it, or if they don't and a mini-series is necessary to tie it all up nicely to satisfy everyone.
