in my mind the way this scene would actually play out is that Fëanor leaps aside in a breathtaking display of elven agility, grabs a torch from a nearby wall-holder, and advances back towards Galadriel holding it up so he can see her face clearly — rather than casually turning his back on her in the middle of a swordfight and wandering off! But the second is more funny.
Note that only the Noldor have swords, so before seeing her face Fëanor would work out that either she picked it up from a dead Noldo, or she's a Noldo (Ñoldië?) herself.
