I'm thinking that it's more likely that Mrs. Acaveda will find out about her husband seeing a hooker and Acaveda beating/sexually assaulting her into a coma/to death when she confronts him.
Either that or he'll break one of the hooker's "rough sex rules" and kills her/put her into a coma after chocking her till she passes out from oxygen deprivation.
I'm better sure the former will happen. He'll get carried away and then. I was just trying to muster up one of the worst images. But I'm thinking Shane's partner will get the axe sometime soon. Then it could split two ways-
Shane grudingly joins back with the Strike Team and it reforms unofficially (the tension, Marla, etc)
Or Shane goes full-fledged on a rampage against Vic because he's afraid he'll foil him.
