there was the glowy alien looking thing. Just what?

Merlin's vision and Mordred's appearance at the end? I must say, Alexander Vlahos has Asa Butterfield's creepy stare down to a T.

And I noticed in the vision scene that Mordred's shoulder guards were etched with the same blood red twin snakes symbol that appeared on the banners from Morgana's vision in "The Darkest Hour." It was a little hard to see, but they were there. Gave me the creeps. I find myself wondering if we're going to see Camlann at the end of the season.

I'm very excited that Mordred is back! I hope he'll be sharing villain duties with Morgana, as I feel Katie McGrath can use someone besides sniveling henchman to bounce off of.

Its better than episode 2. That stupid Klaus thing and Victoria's ridiculously selfish argument just drove me nuts. Also...doesn't it feel like they broke Barney and Quinn up a little quickly?

I loved the episode. Yeah, the broke Barney and Quinn up really fast with little buildup, but I felt that their engagement played out the exact same way. Little buildup and suddenly they were "in love". Anyway, she's gone, won't complain about that. Quinn's character aside, I was thrilled to Barney single again so he could return to form. He's funniest as a character when he's unattached. I also really loved the Lily and Marshall subplot.
