Yes apologies for the long digression about Sauron; it's just a personal interest of mine. My first ever topic here was on the subject of what his attitude towards Morgoth was after the First Age and how much of his agenda was his own.

It might be worth considering this statement from Morgoth's Ring about Melkor/Morgoth's weakening:

"One of the reasons for his self-weakening is that he has given to his 'creatures', Orcs, Balrogs, etc. power of recuperation and multiplication. So that they will gather again without further specific orders. Part of his native creative power has gone out into making an independent evil growth out of his control."

This implies that the Balrogs still had some measure of independence (even if by accident), but perhaps a rather weak one. Maybe it was "waiting" for further orders from Morgoth (which of course never came). Might their "robotic" characteristics, then, perhaps be attributed to the Will of Morgoth being upon them? I'm reminded, for instance, of how when the Ring was destroyed the forces of Sauron were "witless and purposeless". Perhaps without the Will of Morgoth upon it, a Balrog might be somewhat mindless and similarly "purposeless", hence its apparent willingness to stay in Moria for hundreds of years and only emerge if roused by some disturbance or other, and then apparently only by performing what had then become its primary purpose: seeking to destroy.

It seems like a possibility. I wonder the extent to which a Balrog might have recognised Sauron's authority. One would assume that in the First Age, during the times in which Sauron had command (such as when he was in Angband while Melkor was in Valinor, or when Morgoth went forth to spy on Men) he must have had authority over the Balrogs, even Gothmog, who was perhaps only one step below him in the chain of command. If Morgoth was defeated, killed and expelled into the Void, however, and Sauron was now pursuing his own ambition of conquering Middle-earth, might a Balrog recognise this and no longer perceive Sauron as its superior?

Unfortunately, I suspect we'll simply never know.
