Merlin speculations

Well, there were this


There is no reveal.
The final scene of ep 13 is the A/G wedding and crowning
Dragoon is the one who helps Arthur get the sword out of the stone
Gwen will play a vital role in retaking Camelot
Tristan and Isolde will be messed up from the legends

And we know that from them 1 is true, 2 half-true, 2 false.

Let's see: 

There is no reveal - True
The final scene of ep 13 is the A/G wedding and crowning - False (can't be, they shoot it long before coronation), but still could be Half-true if it's next to last one
Dragoon is the one who helps Arthur get the sword out of the stone - Half-true, if 2 is Half-true, than this is False and it's good.
Gwen will play a vital role in retaking Camelot - False
Tristan and Isolde will be messed up from the legends - Half-true, at least they love each other
