What if: Grodus sent the Shadow Queen "back to the depths"

What do you think would have happened if Grodus actually sent the Shadow Queen "back to the depths" like he said he would if she disobeyed him? Would he have kept fighting, given up, or done something else?

I demand that there be no chewing off of heads in this thread if someone disagrees with you (in other words, PLEASE be nice)
 
And yes, I do realize that she killed him before he could do so. This is assuming that she never attempted to do so in the first place
 
it was probably a bluff; i doubt he actually thought he could "unsummon" shadow queen
