Why?? Val only cares about sex, thats it. The only way for Val to be mad is for Husk to prevent Angel from ever seeing him again. So long as Angel is allowed to see Val, Val will SA him whenevr he wants.
Angel and Val arent a couple. Val literally views angel as a sex toy. So he could care less about who angel sleeps with so long as he is able to diddle him whenever he wants.
