Hi Guys!
I just watched the video of what to expect in Season 5 (The video has been posted on the Season 5 page) when I noticed something.

While Katie Mcgrath was talking, an interesting clip showed up. It showed Merlin using magic infront of Gaius AND Gwen! It may just be two random clips put together with the same lighting, but I don't think it is.

This is getting so suspensive and exciting!

So what are your thoughts? And who else do you think Merlin might reveal his secret to?
