For Brad, the only question is, if there is an issue that effects Shannon’s welfare? I want Brad as my son or son-in-law, because he takes charge in looking after the people he cares about, Toni does not fully appreciate the male she had bonded with. His commitment to caring about his “family” is stronger than immediate sex. Shannon has already been adopted by Brad.
Toni just needs to come around to accepting Shannon’s adoption, and realizing that Brad is the best father she could have as a husband.
