''How did Morgana know that Gwen and Elyan would visit Tom's grave? I don't think she was bored and just camped in the woods, waiting for Gwen to pass by. A spy that we'll find out about later maybe (The Dark Tower)?''

Maybe it was the anniversary of Tom's death. Morgana would know the date and could have been aware that Guinevere likes to visit his grave. I wouldn't rule out the spy possibility either, or maybe some kind of scrying or magical spy device.

I've been thinking...if Gwen has been enchanted with magic, then Merlin can easily use his magic to turn her back in the next episode, since his magic is more powerful than Morgana's. However, the plot continues on 5x08, so could it be possible that Gwen is not enchanted and is doing things on her own (The Dark Tower)?

Maybe Morgana has learned her lesson from her experience with Merlin and the fomorrah and, instead of using an enchantment that can be broken by Emrys, she's altered her tactics. She may have used magic to break Guinevere but Guinevere isn't under magical control so much as psychological and emotional control. That means that there's no convenient off-switch. Guinevere could genuinely believe that Morgana is the only person in the world she can count on.

It could also mean that any moves any of the characters make to stop Guinevere will serve to deepen her conviction that they're her enemies and Morgana is her only friend in the world.
