Okay, back to finish my answer. I disagree with 12. I think it is from a series 3 episode where Morgana rides with her cloak on, or maybe Witch's Quickening. 15 is probably Morgause's axe. 16 from the Poisoned Chalice.And 17...to me it looks like Merlin running from the Tomb of Ashkanar in Aithusa!

As for the last flashes:

1) Lancelot's sword, The Darkest Hour

2) Merlin while on Kilgharrah's back, The Tears of Uther Pendragon

3) I agree!

4) ....No idea.

5) Indeed!
