I didn't get to see "Bustin' with Justin" last night, so I can't tell you what happened. I saw bits and pieces, but that was at the bar and the CC wasn't too good.

Baby Lyssa is Barbara and Tucker's full sister, and has a daughter, Abby. Wikipedia has her date of birth listed at 1988, so if that's the case, she must have been VERY young when she had her daughter. They call her "Baby Lyssa" because their mother shares the same name.

When the show started Justin was barely 21 and didn't know any better. My guess is that he simply wasn't ready for this kind of responsibility, his family (who, I don't think, is his blood family anyway) knew that, and A&E decided not to bring him back, and brought Duane Lee in instead.

I know that he took a stab at modeling/acting/music while splitting his time in Colorado, but that's all I know.
