I think they're going to have to go the route of having Fain steal the dagger next episode. Otherwise you have it and Mat both in Tar Valon, and Moiraine wouldn't want the group to leave until she figures out what's going on with him.
We see Fain from two different angles, both standing in a doorway. One where he's watching Rand and Mat walk along the street, and another looking up at them on the balcony.
On the topic of Forsaken - It looked like there were eight statues, so they might be cutting/combining some. Which really isn't surprising. I mean, do we really need Be'lal for example? Also worth noting that they very specifically mentioned that there were eight Aes Sedai sent to capture Logain...
Even better. He had just told her that the gestures were unnecessary and she used that against him.
Also I just want to say poor Mat. He's really breaking...
