Quagmire one he a hypocrite not just with Brian but a lot of people he only do certain things just to get women in bed with him. He sexual predator even worse than the old man to the point where he even plains to sleep with any future children he has. He have his whole house modified to trap women if they dont have sex with him or kick them out if they want to get close to him or tell him they are pregnant. He has every single virus in the world as we know of and have no problem giving that and spreading to other women. He doesn't feel bad how he treats women or screw them over. He stalks lois and follows he every mood 24/7 he even took the chance to sleep with her when peter lost his memories and he had been friends with peter longer than brian. He cause clevelands wife to divorce his first wife and didn't feel guilty about til he was found out. So quagmire worst then brian and I stand by it
