[@Guardian Angel Haruki] Would trying to drag Brutrumukk back to the surface half Rory's movement on top of the half of being in the water?

Huh…

Well, considering that the merrow are currently eating Brutrumukk’s body, I guess you could say it lost some weight. 
However, getting his body away from the merrow would be very difficult. 

I will say some of his belongings dropped to the bottom of the lake.
