That's such a tough question. Basing on other events that made it dead obvious Merlin has to use magic (escaping Morgause's chains, the Fomorroh, and also the scene in The Secret Sharer where Alator made it dead obvious by staring straight at Merlin) I'm quite doubtful. Also, in the vision from The Darkest Hour where Emrys stood over Morgana, and she said 'Help me Emrys, please', it didn't appear she knew who Merlin would have been... but then again she could've just referred to him as Emrys from that point on.

I guess we'll find out. Chances are most likely, she'll have not noticed through all the rubble, or got amnesia.
