Brady is an addict. He trades one for another, whether it is drugs, alcohol, sex, maybe even work. At one time, he & Melanie had a wonderful friendship, the big/brother bestie friend to Mel's lil sis. That is now ruined, just as these writers have purposely, intentionally, ruined every single relationship in Salem, whether it was romantic, friend, or family.
I suppose everyone noted the complete lack of any mention of Valentines, or dates, etc. in Fri. episode. Not a single person.
Brady, in MY opinion, doesn't belong with a babbling 3 yr. old, who turns him into a babbling 10 yr. old.
