I hope it's not that straightforward, but it probably will be. I'd rather that they just showed a few things that we'll never see, to leave a bit of mystery.
Meanwhile, the old sorcerer at the begin = real old Merlin? "He'll recover quickly... if memory serves me well", he said about Arthur. And he looks as if he was chosen for his resemblance to Colin Morgan. Gaius says he was an old seer, who'd died long ago, but could be Merlin sent back in time... would explain easily how he was able to see the future. Or maybe I'm putting too much faith in the writers?
The crystal cave was too similar to the Fortress of Solitude, especially since the stones can be removed and used for other purposes, but it's only one of many Smallville comparisons in the show. One more can't hurt.
Morgause has really neat mirror writing.
Everything Merlin saw in the crystals happened.
HOW DARE YOU TREAT ME SUCH!!!!!!!!!!!!!??????????
Anyway, overall a really good episode, with a dreamy, melancholy feel in some places. Morgana being Arthur's half sister seems a bit odd considering Uther was trying to get them to marry, iirc, but then they did use to do that sort of thing. The way Uther kept trying to tell Gaius to use magic and how he thanked him at the end were really good. And it makes Uther even more evil. Merlin nearly killing Morgana was kind of hardcore, though I'm not really sure why he's so determined to save Uther.
Maybe next week's is just a repeat. I'm sure I've heard "I will watch you grow into the King Camelot deserves" before.
