User blog:It's Good to be the Queen/5 x 09 - the end of the Gwen/Morgana "friendship"

We all know by now Gwen has been enchanted by Morgana to do her dirty work to try to kill Arthur so she can take the throne. A new teaser line from 5 x 09 I think definitely comfirms it:

"“This ***** (?) was ****** (trash) in a ******’s (queen's) ****** (dress) and it will do my bidding” [I'm guessing at the asterisked words here]

The preview of 5 x 09 states Arthur finds out about Gwen with his own eyes. He and Merlin follow Gwen to her rendevous with Morgana, where Gwen gives plans Morgana to a levy route Arthur will go on. That when he'll be ambushed and killed. Most likely the route will go as scheduled but they will be ready for an attack, with enough forces to try to take Morgana. When word gets back to Morgana that this assassination attempt failed (who's surprised here?) and her forces have been captured or killed (how is she paying for these people?) she's going to figure out Arthur now knows about Gwen. I'm not sure if Morgana will think Gwen gave her up to save herself, but at this point, Gwen has become expendable. When her willing or unwilling spies get caught one way or another Morgana throws them under the bus (see Sefa 5 x 02). For Gwen Morgana is going to torture Arthur by maintaining control, weakening him enough to go in for the kill. Once Arthur is dead, she will dispose of Gwen. (I still don't understand why Gwen thinks she will remain alive once Morgana takes the throne.)  I think some harsh truth coming from Morgana's mouth for Gwen to hear is going to be the catalyst to start to break the spell. Hence the line.

Thoughts?
